If you’re looking for some great ideas for class science projects, you’ve come to the right place! In this article, we’ll give you some tips on how to choose a project that’s both interesting and educational.

We know that coming up with science project ideas can be tough, so we’ve compiled a list of some awesome ideas to get you started. Whether you’re interested in studying the stars or investigating the properties of matter, there’s a project here for you!

Remember, the best projects are those that are both fun and informative. So take your time in choosing a topic, and make sure to consult your teacher before getting started. With these guidelines in mind, you’re sure to create a masterpiece!

There are a number of really great ideas for class 7 science projects. These can be done with just a few laboratory items and a little bit of knowledge about how circuits work. These are the fun project that can be done over the course of a few weeks. 

A glass of water is a great way to get started with your science project. Not only is it an easy and inexpensive way to get started, but you can also use it to learn about the properties of water and how they change when different substances are added to it.

You can also use it to study the effects of temperature on water and how different liquids mix together.

When it comes to exploring the science behind swim bladders, there are a few key things to keep in mind.

First, swim bladders are gas-filled sacs that help fish maintain their buoyancy.

Second, the size and shape of a fish’s swim bladder can vary depending on the species.

And lastly, there is some evidence to suggest that fish with swim bladders may be able to sense changes in water pressure and temperature.

Bubbles are always a hit with kids, so why not incorporate them into a science project?

There are two ways to blow bubbles – with hot air or cold air. Try both methods and see which one produces bigger bubbles.

You can also experiment with different types of soap to see which one makes the strongest bubbles.

If you’re looking for a fun and engaging way to learn about angular momentum, then look no further than Beyblade spinning toys. By spinning a Beyblade around its axis, students can observe firsthand how angular momentum affects an object in motion.

You can also experiment with different blade shapes and sizes to see how they affect the toy’s spin.

There are many different types of oxidation that can be explored through class 7 science projects. One example is rust, which is the oxidation of iron. 

This can be explored by testing different methods of preventing rust, such as painting or coating iron in a protective layer.

Other types of oxidation include the fading of colors and the decomposition of materials. These processes can be accelerated and monitored through experiments.

Generating electricity is a process of converting one form of energy into another. In this science experiment, we will be using our bodies to generate electricity.

First, we will take one of the alligator clip wires and attach it to the positive side of the battery.

 Then, we will take the other alligator clip wire and attach it to the negative side of the battery. Finally, we will touch the two wires together, which will cause the light bulb to light up!

This experiment is a great way to learn about how electricity is generated and used in our everyday lives.

When creating a taxonomy system for a class 7 science project, it is important to consider what information will be most useful for the project.

For example, if the focus of the project is on plants, then including information on kingdom and phylum would be most helpful. 

If the focus of the project is on animals, then including information on class and order would be most helpful.

Once you have decided what information will be most useful for the project, you can begin creating your taxonomy system.

In this project, students will learn about the engineering principles used by Leonardo da Vinci to design his famous bridge. They will then use these same principles to build their own bridges out of popsicle sticks and glue.

This is a great project for teaching the basics of engineering and physics .  

Students will use popsicle sticks and glue to build a replica of the famous da Vinci bridge.

This project is perfect for students who are interested in engineering and architecture. In addition to being a fun and engaging class 7 science project, this experiment will also teach students about the science of bridges. 

A pinball machine is a great way to teach the scientific method to kids. With this experiment, they will learn how to design and build a simple pinball machine. They will also learn about the physics of motion and energy. 

First, cut a hole in the cardboard. This will be the starting point for your ball. Next, tape three paper cups upside down on the cardboard. These will be your targets. Finally, cut a small slit in the bottom of each cup. The ball will fall through these slits when hit.

Now it’s time to test your machine! Drop the ball from the top of the cardboard and see how it does. Does it hit all the targets? Does it go off the edge of the cardboard? Make adjustments until you are happy with your design.

Color has been shown to affect memory in a variety of ways.

For instance, one study found that participants were better able to remember words that were presented in red font if the words had a positive connotation (e.g., love, happy), but they were better able to remember words that were presented in blue font if the words had a negative connotation (e.g., sad, evil).

These findings suggest that color can influence memory by affecting how we process and encode information.

Therefore, if you’re working on a class 7 science project about memory, you may want to experiment with different colors to see how they impact memory recall.

To collect and control biofilm, students will need to understand what it is and how it forms. A biofilm is a slimy substance that contains bacteria, fungi, and other microorganisms. It can form on wet surfaces, such as in pipes or on teeth.

To control biofilm, students will need to learn about the different methods of cleaning and disinfecting surfaces.

They will also have to understand how biofilm can be used to benefit humans, such as in the production of certain medications or in the treatment of sewage.

 If you’re looking for some ideas for your next class 7 science projects, why not try a hydraulic power experiment?

Hydraulic power is the force that is generated when water is under pressure. By using this force, we can do things like lift heavy objects or move vehicles. In this experiment, you will be using hydraulic power to move a small object.

Fill your container with water and add a few drops of food coloring if you like. Place your object in the center of the container.

Make sure that the top of the object is level with the water line.

Now, apply pressure to one side of the container with your hand. You should see the object start to move!

Try different amounts of pressure to see how it affects the speed of movement. Can you make the object move faster or slower? 

There are many ways to test for the presence of germs, but one of the most common is to swab an area and then test the swab for bacteria or other microorganisms. This can be done using a variety of methods, including microscopy, culture plates, and DNA sequencing.

Copper-plating coins is a great way to add a personal touch to your pocket change. This project is perfect for kids who are interested in science and chemistry.

First, clean your coins with the distilled water and dry them off. Next, cut the copper into small strips using scissors or wire cutters.

Attach one end of the copper strips to the positive terminal of the battery with an alligator clip.

Then, touch the other end of the copper strip to the negative terminal of the battery. Finally, dip your coins into the solution and wait a few minutes for them to turn green.

Too often, we get bogged down in the same old routines and fail to see the beauty and excitement that surrounds us everyday.

One way to combat this rut is to challenge your brain with new experiences. A great way to do this is through flexibility experiments.

Flexibility experiments are a fun way to explore the world around you while also growing your mental capacity. By their very nature, they force you to think outside the box and come up with new ways to approach problems. This makes them perfect for science class projects.

There are endless possibilities when it comes to flexibility experiments. You could try something as simple as seeing how long you can hold a handstand or how far you can stretch without moving your feet.

Or, you could get really creative and build a Rube Goldberg machine that accomplishes a simple task in the most complicated way possible.

No matter what you choose to do, flexing your mental muscle with a flexibility experiment is sure to be a fun and enlightening experience!

There are many ways to extract DNA from an onion, but we will outline two of the most popular methods.

The first method is to cut the onion in half and then use a blender or other tool to blend it up into a liquid.

Once the onion is liquified, add some dish soap and stir. The dish soap will break down the cell walls of the onion and release the DNA. 

Then, pour the mixture into a strainer to remove any solids. Finally, add some isopropyl alcohol to the liquid and gently swirl.

The DNA will precipitate out of solution and collect at the bottom of the container. You can then scoop it out with a spoon or pipette.

Sugary drinks are often high in acidity, which can lead to tooth enamel erosion.

In this experiment, students will investigate how sugary drinks affect teeth by placing eggshells in different types of sugary drinks and observing the changes over time.

Collect a few eggshells and clean them thoroughly. Allow them to dry completely. Fill three glasses with water and label them “control”. Add one eggshell to each glass.

Fill three other glasses with different sugary drinks and label them accordingly. Add one eggshell to each glass.

Observe the eggshells in the control group after 24 hours, 48 hours, and 72 hours. Record your observations in a table or chart.

Repeat step 4 for the eggshells in the sugary drink group. Compare your results between the two groups of eggshells!

There are a ton of ways to make slime, but here is one way to design your own slime:

In a bowl, mix together the glue and water. Add food coloring, glitter, and any other desired add-ins to the bowl and mix together.

In a separate bowl, mix together 1/2 tsp borax powder with 1/4 cup water. Stir until the borax is dissolved. Pour the borax mixture into the glue mixture and stir until combined. The slime will start to form immediately.

Once everything is mixed together, knead the slime with your hands until it reaches the desired consistency. If it’s too sticky, add a bit more borax powder; if it’s too stiff, add a bit more water. And that’s it – you’ve made your very own slime!

Cut a small hole in the bottom of your container. The hole should be big enough to fit the end of your ruler or measuring tape. Fill your container with water. You can add food coloring to the water if you like. 

Place the container on a flat surface and insert the ruler or measuring tape through the hole in the bottom. The end of the ruler or measuring tape should be touching the bottom of the container.

Use the permanent marker to mark where the water level is on the outside of the container. This will be your starting point. Wait 1 hour and then use the permanent marker to mark where the water level is again. This will be your ending point.

Measure the distance between your starting point and ending point. This is how much water has flowed out of your container in 1 hour!

If you’re looking for an awesome science project, why not try riding the wave machine? This is a great project for anyone interested in physics or engineering, and it’s sure to be a hit with your classmates. Here’s what you’ll need to do to get started:

Build your own wave machine. You can find plenty of instructions online or in science textbooks. Experiment with different materials to see what works best. Some good options include cardboard, wood, foam, and plastic.

Once you have your machine built, test it out! See how high you can make the waves and how long they last. Make observations and take measurements throughout your experiment. Be sure to record all of your data so that you can analyze it later.

Present your findings in a detailed report or presentation. Include information on your design, testing process, results, and conclusions.

When it comes to Science projects, there are many different ways to purify water. One popular method is using charcoal. This experiment will show you how effective charcoal is at purifying water.

Pour the cup of water into the bowl. Add the activated charcoal to the water and stir. Place the coffee filter or cloth over the top of the bowl and allow the mixture to sit for 15 minutes.

After 15 minutes, remove the coffee filter or cloth and observe the filtered water. You should notice that it is much clearer than when you started!

First, you’ll need to gather your materials. You’ll need a head of cabbage, red wine vinegar, water, a glass jar or container, a measuring spoon, and pH strips. You’ll also need blue food coloring if you want to see the pH change color as it happens.

To start, cut the cabbage into small pieces and add it to the jar or container. Add equal parts red wine vinegar and water to the cabbage (1/2 cup each should be enough). If you’re using food coloring, add a few drops of blue food coloring to the mixture now.

Place the lid on the jar or container and give it a good shake until everything is mixed together well. Let the mixture sit for at least 24 hours so that the cabbage has time to release its natural pH indicator – this is what will show you how acidic or basic your solution is on the pH scale.

After 24 hours have passed, it’s time to test your solution! Take a pH strip and dip it into the liquid in the jar or container. Compare the color of the strip to the chart that came with your pH strips – this will tell you where your solution falls on the pH scale (acidic, neutral, or basic).

To measure the amount of energy that is stored in various types of food, we will need to conduct an experiment. In this experiment, we will be burning calories to see how much energy is released.

Place the food item on the balance scale and weigh it. Record the weight in your data table. Place the food item on a heat-proof surface. Ignite it with a match and start the stopwatch or timer. Record the time in your data table. 

Allow the food item to burn completely. Once it has burned out, weigh the ashes on the balance scale and record the weight in your data table. Calculate the amount of energy released by the food by subtracting the weight of the ashes from the original weight of the food item.

This will give you grams of lost weight due to combustion. Energy release is measured in kilojoules/kilocalories (kJ/kcal), so use your calculator to convert grams lost to kJ/kcal lost using this formula: kJ/kcal = 4184 x grams lost

Coding with LEGO bricks is a great way to introduce kids to the basics of computer programming. By following simple instructions, they can create programs that make their LEGO creations move and interact with each other. This is a great way to get kids interested in coding, and it’s also a lot of fun! 

Coding with LEGO is a great way for kids to learn the basics of coding. By experimenting with different code blocks, they can learn how to create simple programs and games . Plus, it’s a lot of fun!

 A density rainbow is a beautiful and easy way to learn about density ! All you need is a clear container, some water, food coloring, and a few common household objects.

To make your density rainbow, start by filling the container with water. Add a few drops of food coloring to the water, and then carefully add your objects one at a time. Be sure to add them in order from heaviest to lightest!

Once all of your objects are in the water, take a step back and admire your handiwork. The different colors of the food coloring will show you which object is denser than the others. The heaviest object will be at the bottom of the container, while the lightest object will float on top!

30 Ideas For 7th Grade Science Fair Projects

By Beth Roberts | Last Updated May 4, 2022

We’ve compiled some of the best seventh grade science fair projects for your convenience! These science fair project ideas for 7th graders are sure to get you inspired and ready to do go on your own amazing research. We’ve also provided a list of resources you can use at home or in the classroom that will help give you tips on how to start your project, how to present it, and how to write an awesome science fair paper.

1. Drive A Balloon-Powered Car

This is an easy to build science fair project that you can even do with your younger brothers and sisters. You will need a high-quality balloon, scissors, tape, paperclip and a ruler.

First you will want to cut off the end of the balloon just above where half of it already has a hole in it. Then thread the tape through the hole so that it is on one side and stick the paperclip through it (close to the bottom of the balloon). Now take your ruler and measure how long it is going to be. When measuring however, you have to make sure that you are going to cut past where half of your paperclip is.

2. Make A Bionic Hand

This project involves making a bionic hand out of rubber and plastic parts and will involve cutting, gluing and soldering. You will want to be careful when cutting this project as you can seriously injure yourself if you cut too close to the plastic so make a good outline before doing it. First you will want to find out how big your hand is going to be. Then draw that on the rubber sheet with a pencil (minus the thumb where it will be). Measure how long your hand is going to be from top to bottom then measure 1/4″ from all 4 sides (you want 4 measurements).

3. Do An Experiment On The Physical Properties Of Water

This seventh grade science fair project assumes you already know some things about the physical properties of water. You will want to do this experiment with a partner who also knows some things about water. First you will want to find out whether or not your partner is willing to do this experiment with you and then measure out how many 1/2 cups of water there are in a gallon. Then take a sample of that and measure it again, this time in 1/4 cups. Then you will want to find out how many 4 oz cups are in your sample, then 1 cup and then 2 cups. Now take your results and do what is called an average of those measurements in a data table like this.

4. Make A Tornado In A Bottle

This project is somewhat easy but it may take some time to get right . You will want to do this by yourself as you can be seriously injured if you do the wrong thing. First you will want to take your empty soda bottle and rinse out all of the soda from it. Then make sure there is no water left in the bottle from rinsing it then soak it in water for about 20 minutes. After your 20 minutes are up, shake the water out of the bottle, but make sure you leave enough that it will not leak out as soon as you put in your dry ice (if you use dry ice).

5. Sorting Jellybeans is a Fun way To Learn about Heredity.

Use the following pointers to sort jellybeans :

a. Jellybeans come in blue, yellow, orange and pink jellybean colors (you can use colored paper and a different color of pen)

b. Jellybeans are round (you can use a ruler)

c. The outside edge of each jellybean is the “seam” that runs down the middle of the jellybean (you will be able to see this clearly after you fill the bag) 

6. Allow A Teabag To Float In The Air

This experiment is best done outside. First you will want to take a tea bag and put it in a glass of water , then carefully place it on top of the water in the cup. Make sure there is plenty of room between the cup and the tea bag (this will allow for air to circulate and help it to float). Watch as your teabag floats in mid-air!

7. Make A Slime Bomb

This science fair project is best done with an adult or older kid . You will want to find out what chemicals to use for the slime (you can search the internet for that) and then make it. It is best if you have a friend who knows how to make slime with you, too!

8. Build A Mini Catapult And Launch Yourself Across The Room

This science fair project can be fun , but it does take some time to get right. You will need several objects to build a mini catapult out of: a small stick, tape, string, paperclips and cans (for launching).

9. Make A Vacuum Cleaner Powered Fan

This science fair project is fun , but it can be dangerous. You will want to do this in an area where you do not have many dangerous electrical cords nearby and make sure you can easily get out of the way if it starts to fly off the ground. You will need a fan, a handheld vacuum, scissors and paperclips. First you will want to take apart your handheld vacuum and find the blade part of it. You will want to cut out about 1/2″ of the rubber around the blade. Then tape that on one side of your fan (make sure you have 2 blades facing each other).

10. Make A Solar Oven Design.

Students explore thermal energy, reflection, convection, and other physics principles as they experiment with the best way to create a solar oven . They’ll be able to serve up their experiment findings as well as their final reports!

11. Make A Rocket Powered By Dry Ice.

This is a science fair project that is best accompanied with someone who has done this before. You will want to make sure you are in an open area where you can easily get out of the way if it does not work.

First you will want to use a craft knife to cut out the bottom part of a soda bottle, making sure that you leave about 1/4″ on the bottom so it does not leak. About halfway up you will want to then cut off another part (this will be used for your air intake) and make sure your intake side is smaller than your exhaust side. Cut as close as possible so that they are seamless together.

12. Make Your Own Lava Lamp

This is a fun science fair project that involves melting wax and oil together . You will want to make sure you have something to put this in (a bottle, jar or plastic cup would work). You will need: red food coloring, water, dish detergent, oil (olive or vegetable), and that small globe from a lava lamp you might have lying around the house.

13. Take A Look At How The Greenhouse Effect Works.

The greenhouse effect is a natural phenomenon that can be observed in the Earth’s atmosphere on a daily basis. Many people are unaware of how it works and how much it affects our lives. This project encourages students to gain a better understanding of the greenhouse effect and its impact on Earth’s temperature.

14. Use Water Color To Make Your Own Kaleidoscope

You can use a permanent marker, paint or crayon. By varying the size and shape of the dots, you can create many different patterns in your result. Study how light is reflected in two and three dimensions of the pattern.

15. A Dense Rainbow Is Awe-Inspiring.

Density is the same as mass divided by volume . It is a measure of how tightly packed together molecules of matter are. This project forces students to learn about density in order to obtain a rainbow of monochromatic liquids in graduated cylinders that vary in size. The light source and liquid arrangement allows them to observe the density spectrum of each liquid.

16. Use Charcoal To Purify Water.

Water is one of the most important substances on Earth . It keeps us alive, purifies us and is also used to grow crops. Many people do not have access to clean drinking water and this project will help them by guiding them in the creation and use of charcoal for use in a filter for water purification.

17. Find Out How Energy Is Transformed.

Energy can be transformed from one form to another , but often loses some of its original properties. This project highlights the effects on a car battery if it is connected to a series of light bulbs and a conducting wire.

18. Make Your Own Tesla Coil.

Invented by Nikola Tesla in 1891, the Tesla Coil is an electrical resonant transformer circuit capable of producing extremely high voltages using an air-core transformer based on two spark gaps and two capacitors that allow alternating current through the primary coil to build up an oscillating high voltage in the secondary coil without requiring any type of power source with wires directly attached to it like you would find in conventional coils.

19. Coat Some Coins With Copper.

Copper-plating gives a metallic luster and color to many things , such as coins, jewelry, and even small kitchen utensils. In this project, students will use copper sulphate solution to convert a penny into a shiny plated coin.

20. Play With Hydraulics To See What You Can Come Up With.

Hydraulics is the study of fluids at rest or in motion and the mechanical devices that are directed by them. This project will allow students to learn about how pressure and force can be used to create movement and power.

21. Biofilms Should Be Collected And Managed.

Biofilms are naturally occurring communities of microorganisms , usually bacteria but also fungi and algae cells. Biofilms are found in almost all natural environments and on most man-made surfaces. They consist of living microbes that can persist for long periods, while producing tranquil points which may be as much as 100 times greater than their own area. This project introduces students to biofilms in order to encourage them to observe how they grow and how they are treated during the experiments.

22. Using Experiment Kits On Baking Soda And Vinegar, Make A Volcano.

An erupting volcano is an impressive sight to many people , but they are also extremely dangerous! In this experiment, students will learn about what causes volcanoes to erupt and what type of rocks are needed to build them with their own hands.

23. Crystals Are Fun To Grow And Play With.

Crystals are beautiful, fascinating and useful . Students will learn about how crystals grow by experiencing it themselves and observing the different ways they can form, with the help of a variety of experiment kits. This is a hands-on science experiment that encourages students to be creative, experience sensory impact and develop an intuitive understanding of materials as they work with them in real time.

24. Explore The Laws Of Motion Using A Spinner.

Gyroscopes are used in many aspects of our everyday lives .

Science is considered as one of the difficult subjects including both theory and practical application. Students of Class 7th learn to make working models and understand it’s applications. There are various science projects for class 7th students that are given by the teachers. Students are allowed to make a group of 3 – 5 members to coordinate accordingly and make the model. These models are in a form of the diagram that the students must have seen as a kid in various commercials.  

The students working together develop skills like teamwork, leadership skills, synchronization and much more. These skills help the students in the long run for other future prospects. These scientific models somehow explain the behaviour of the systems in the real world i.e. how do they react to natural calamities or how are they made and used. 

These models are made to make the concepts easier. Students understand whatever they have learnt in the classroom lectures through creating these working models. Students enjoy making such models with an understanding of interesting facts from subjects like Physics, Chemistry, Biology, Earth and many more. Below are some of the working models that students make in order to simplify the concepts of science.

FactChecking the Biden-Trump Debate

In the first debate clash of the 2024 campaign, the two candidates unleashed a flurry of false and misleading statements.

By Robert Farley , Eugene Kiely , D'Angelo Gore , Jessica McDonald , Lori Robertson , Catalina Jaramillo , Saranac Hale Spencer and Alan Jaffe

Posted on June 28, 2024

The much-anticipated first debate of 2024 between President Joe Biden and former President Donald Trump featured a relentless barrage of false and misleading statements from the two candidates on immigration, the economy, abortion, taxes and more.

• Both candidates erred on Social Security, with Biden incorrectly saying that Trump “wants to get rid” of the program, and Trump falsely alleging that Biden will “wipe out” Social Security due to the influx of people at the border.
• Trump misleadingly claimed that he was “the one that got the insulin down for the seniors,” not Biden. Costs were lowered for some under a limited project by the Trump administration. Biden signed a law capping costs for all seniors with Medicare drug coverage.
• Trump warned that Biden “wants to raise your taxes by four times,” but Biden has not proposed anything like that. Trump was also mostly wrong when he said Biden “wants the Trump tax cuts to expire.” Biden said he would extend them for anyone making under $400,000 a year.
• Biden repeated his misleading claim that billionaires pay an average federal tax rate of 8%. That White House calculation factors in earnings on unsold stock as income.
• Trump repeated his false claim that “everybody,” including all legal scholars, wanted to end Roe v. Wade’s constitutional right to abortion.
• Trump falsely claimed that “the only jobs” Biden “created are for illegal immigrants and bounced back jobs that bounced back from the COVID.” Total nonfarm employment is higher than it was before the pandemic, as is the employment level of native-born workers.
• Biden claimed that Trump oversaw the “largest deficit of any president,” while Trump countered that “we now have the largest deficit” under Biden. The largest budget deficit was under Trump in fiscal year 2020, but that was largely because of emergency spending due to COVID-19.
• Biden misleadingly said that “Black unemployment is the lowest level it has been in a long, long time.” The rate reached a record low in April 2023, and it was low under Trump, too, until the pandemic.
• Biden said Trump called U.S. veterans killed in World War I “suckers and losers,” which Trump called a “made up quote.” The Atlantic reported that, based on anonymous sources. A former Trump chief of staff later seemed to confirm Trump said it.
• Trump claimed that Biden “caused the inflation,” but economists say rising inflation was mostly due to disruptions to the economy caused by the pandemic.
• Trump grossly inflated the number of immigrants who have entered the country during the Biden administration — putting the number at 18 million to 20 million — and he said, without evidence, that many of them are from prisons and mental institutions.
• Trump claimed that “we had the safest border in history” in the “final months” of his presidency. But apprehensions of those trying to cross illegally in the last three full months of his presidency were about 50% higher than in the three months before he took office.
• Biden criticized Trump for presiding over a loss of jobs when he was president, but that loss occurred because of the COVID-19 pandemic.
• Trump falsely claimed that “some states” run by Democrats allow abortions “after birth.” If it happened, it would be homicide, and that’s illegal.
• Trump made the unsupported claim that the U.S. border with Mexico is “the most dangerous place in the world,” and suggested that it has opened the country to a violent crime wave. The data show a reduction in violent crime in the U.S.
• Trump overstated how much food prices have risen due to inflation. Prices are up by about 20%, not double or quadruple. 
• Trump boasted his administration “had the best environmental numbers ever.” Trump reversed nearly 100 environmental rules limiting pollution. Although greenhouse gas emissions did decline from 2019 to 2020, the EPA said that was due to the impacts of the pandemic on travel and the economy.   
• Biden said he joined the Paris Agreement because “if we reach the 1.5 degrees Celsius, and then … there’s no way back.” Limiting global warming to 1.5 degrees would reduce the damages and losses of global warming, but scientists agree that climate action is still possible after passing the threshold.
• Trump said immigrants crossing the border illegally were living in “luxury hotels.” New York City has provided hotel and motel rooms to migrant families, but there is no evidence that they are being placed in “luxury” hotels. 
• Trump falsely claimed that there was “no terrorism, at all” in the U.S. during his administration. There were several terrorist acts carried out by foreign-born individuals when he was president.
• While talking about international trade, Trump falsely claimed that the U.S. currently has “the largest deficit with China.” In 2023, the trade deficit in goods and services with China was the lowest it has been since 2009.
• Trump wrongly claimed that prior to the pandemic, he had created “the greatest economy in the history of our country.” That’s far from true using economists’ preferred measure — growth in gross domestic product.
• As he has many times before, Trump wrongly claimed, “I gave you the largest tax cut in history.” That’s not true either as a percentage of gross domestic product or in inflation-adjusted dollars.
• Trump contrasted his administration with Biden’s by misleadingly noting that when he left office, the U.S. was “energy independent.” The U.S. continues to export more energy than it imports.

The debate was hosted by CNN in Atlanta on June 27.

Social Security

Biden claimed that Trump “wants to get rid” of Social Security, even though the former president has consistently said he will not cut the program and has advised Republicans against doing so.

Earlier this year, Biden and his campaign based the claim on Trump saying in a  March 11 CNBC interview  that “there is a lot you can do in terms of entitlements in terms of cutting and in terms of also the theft and the bad management of entitlements.” As  we’ve said , in context, instead of reducing benefits, Trump was talking about cutting waste and fraud in those programs — although there’s not enough of that to make the program solvent over the long term.

“I will never do anything that will jeopardize or hurt Social Security or Medicare,” Trump later said in a  March 13 Breitbart interview . “We’ll have to do it elsewhere. But we’re not going to do anything to hurt them.”

During the GOP presidential primary, Trump also  criticized  some of his Republican opponents for proposing to raise the retirement age for Social Security, which budget experts  have said  would reduce scheduled benefits for those affected.

Some critics of Trump have  argued  that he cannot be expected to keep his promise because of his past budget proposals. But,  as we’ve written , Trump did not propose cuts to Social Security retirement benefits.

Meanwhile, Trump claimed during the debate that Biden “is going to single handedly destroy Social Security” because of illegal immigration. “These millions and millions of people coming in, they’re trying to put them on Social Security. He will wipe out Social Security,” Trump said of Biden.

As  we  and  others  have explained before, immigrants who are not authorized to be in the U.S. aren’t eligible for Social Security. In fact, because many such individuals pay into Social Security via payroll taxes but cannot receive benefits, illegal immigrants bolster rather than drain the finances of the program.

In referring to what seniors pay for insulin, Trump misleadingly claimed, “I heard him say before ‘insulin.’ I’m the one that got the insulin down for the seniors. I took care of the seniors.” Insulin costs went down for some beneficiaries under a limited project under Trump; Biden signed a more expansive law affecting all seniors with Medicare drug coverage.

Under Trump, out-of-pocket costs were lowered to $35 for some Medicare Part D beneficiaries under a two-year pilot project in which some insurers could voluntarily reduce the cost for some insulin products. KFF, a nonpartisan health policy research organization,  explained  earlier this month that under this model, in effect from 2021 to 2023, “participating Medicare Part D prescription drug plans covered at least one of each dosage form and type of insulin product at no more than $35 per month,” and “less than half of all Part D plans chose to participate in each year.”

But in 2022, Biden  signed a law  that required all Medicare prescription drug plans to cap all insulin products at $35. The law also capped the out-of-pocket price for insulin that’s covered under Medicare Part B, which covers drugs administered in a health care provider’s office. The caps went into effect last year.

STAT, a news site that covers health care issues,  reported  that the idea for a $35 cap for seniors initially came from Eli Lilly, the pharmaceutical company, which proposed it in 2019.

Trump on Biden Tax Plan

“He’s the only one I know he wants to raise your taxes by four times,” Trump said of Biden. “He wants to raise everybody’s taxes by four times. He wants the Trump tax cuts to expire. So everybody … [is] going to pay four to five times –  nobody ever heard of this before.”

Trump regularly warns of massive tax hikes for “everybody,” should Biden be reelected. That doesn’t jibe with anything Biden has proposed.

In his more than three years as president, Biden’s  major tax changes  have included setting a  minimum corporate tax rate  of 15% and lowering taxes for some families by  expanding the child tax credit  and, for a time, making it fully refundable, meaning families could still receive a refund even if they no longer owe additional taxes.

As  we wrote  in 2020, when Trump made a similar claim, Biden proposed during that campaign to raise an additional $4 trillion in taxes over the next decade, although the increases would have fallen mainly on very high-income earners and corporations. The plan would not have doubled or tripled people’s taxes at any income level (on average), according to analyses of Biden’s plan by the  Penn Wharton Budget Model ,  the Tax Policy Center  and  the Tax Foundation .

In March 2023, the TPC’s Howard Gleckman  wrote  that Biden proposed a 2024 budget that would, on average, increase after-tax incomes for low-income households and “leave them effectively unchanged for middle-income households.” The Tax Policy Center noted, “The top 1 percent, with at least roughly $1 million in income, would pay an average of $300,000 more than under current law, dropping their after-tax incomes by 14 percent.”

This March, Biden released his  fiscal year 2025 budget , which contains many of the same proposals and adds a few new wrinkles. But it still  does not contain  any “colossal tax hikes” on typical American families, as Trump has said.

Biden’s latest plan proposes — as he has in the past — to increase the corporate income tax rate from 21% to 28%, and to  restore  the top individual tax rate of 39.6% from the current rate of 37%. It would also increase the corporate minimum tax rate from 15% to 21% for companies that report average profits in excess of $1 billion over a three-year period. And the plan would impose a 25% minimum tax on very wealthy individuals. The plan also proposes to extend the expanded child tax credit enacted in the American Rescue Plan through 2025, and to make the child tax credit fully refundable on a permanent basis.

Trump is also mostly wrong that Biden “wants the Trump tax cuts to expire.”

As he has said since the 2020 campaign, Biden’s FY 2025 budget vows not to increase taxes on people earning less than $400,000.

In order to keep that pledge, Biden would have to extend most of the individual income tax provisions enacted in the Tax Cuts and Jobs Act that are set to expire at the end of 2025. And that’s what Biden says he would do — but  only for  individual filers earning less than $400,000 and married couples making less than $450,000. (In order to pass the TCJA with a simple Senate majority, Republicans wrote the law to have most of the individual income tax changes  expire after 2025 .)

The Biden budget plan “would raise marginal income tax rates faced by higher earners and corporations while expanding tax credits for lower-income households,” according to a Tax Foundation  analysis  of the tax provisions in Biden’s budget. “The budget would redistribute income from high earners to low earners. The bottom 60 percent of earners would see increases in after-tax income in 2025, while the top 40 percent of earners would see decreases.”

Biden on Taxes Paid by Billionaires

In arguing that wealthy households should pay a minimum tax, Biden repeated his misleading claim that billionaires pay an average federal tax rate of 8%.

“We have a thousand … billionaires in America, and what’s happening?”  Biden said . “They’re in a situation where they in fact pay 8.2% in taxes.”

That’s not the average rate in the current tax system; it’s a figure  calculated  by the White House and factors in earnings on unsold stock as income. When only considering income, the top-earning taxpayers, on average, pay higher tax rates than those in lower income groups, as  we’ve written  before.

The top 0.1% of earners pay an average rate of 25.1% in federal income and payroll taxes,  according to  an analysis by the Tax Policy Center in October 2022 for the 2023 tax year.

The point that Biden tried to make is that earnings on assets, such as stock, currently are not taxed until that asset is sold, which is when the earnings become subject to capital gains taxes. Until stocks and assets are sold, the earnings are referred to as “unrealized” gains. Unrealized gains, the White House  has argued , could go untaxed forever if wealthy people hold on to them and transfer them on to heirs when they die.

Roe v. Wade

As he has  before , Trump wildly exaggerated the popularity of ending Roe v. Wade — even going so far as to claim that it was “something that everybody wanted.”

“51 years ago, you had Roe v. Wade and everybody wanted to get it back to the states,”  he said , referring to the 1973 Supreme Court ruling that established a constitutional right to abortion, which was  overturned  in 2022.

Trump:  Everybody, without exception: Democrats, Republicans, liberals, conservatives. Everybody wanted it back — religious leaders. And what I did is I put three great Supreme Court justices on the court and they happened to vote in favor of killing Roe v. Wade, and moving it back to the states. This is something that everybody wanted. Now 10 years ago or so they started talking about how many weeks and how many this and getting into other things. But every legal scholar throughout the world — the most respected — wanted it brought back to the states. I did that.

In fact, a majority of Americans have disagreed with ending Roe v. Wade, including plenty of legal scholars, as we’ve explained  before . While some scholars criticized aspects of the legal reasoning in Roe, it did not necessarily mean they wanted the ruling overturned. Legal experts told us that Trump’s claim was “utter nonsense” and “patently absurd.”

Trump Wrong on Jobs

After Biden talked about job creation during his administration, Trump falsely claimed that “the only jobs [Biden] created are for illegal immigrants and bounced back jobs that bounced back from the COVID.”

In fact, as of May,  total nonfarm employment  in the U.S. had gone up about 6.2 million from the pre-pandemic peak in February 2020, according to figures from the Bureau of Labor Statistics. The increase is about 15.6 million if you count from when Biden took office in January 2021 until now — but that would include some jobs that were temporarily lost during the pandemic and then came back during the economic recovery.

Furthermore, there is no evidence that only “illegal immigrants” have seen employment gains.

Since Biden became president in January 2021, employment of U.S.-born workers has increased more than employment of foreign-born workers, a category that includes anyone who wasn’t a U.S. citizen at birth, as we’ve written before . BLS says the  foreign-born  population includes “legally-admitted immigrants, refugees, temporary residents such as students and temporary workers, and undocumented immigrants.” There is no employment breakdown for just people in the U.S. illegally.

In looking at employment since the pre-pandemic peak, the employment level of  foreign-born workers  was up by about 3.2 million, from roughly 27.7 million in February 2020 to nearly 30.9 million in May. Employment for the  U.S.-born population  increased by about 125,000 — from nearly 130.3 million in February 2020 to 130.4 million, as of May.

Conflicting Budget Deficit Claims

Biden and Trump accused each other of presiding over the largest budget deficit in the U.S.

After talking about Trump’s plans for additional tax cuts, Biden said Trump already had the “largest deficit of any president in American history.” When he got a chance to respond, Trump said, “We now have the largest deficit in the history of our country under this guy,” referring to Biden.

Biden is correct: The  largest budget deficit  on record was about $3.1 trillion in fiscal year 2020 under Trump. However, that was  primarily  because of trillions of dollars in emergency funding that both congressional Republicans and Democrats approved to address the COVID-19 pandemic. Before the pandemic, the largest budget deficit under Trump was about $1 trillion in fiscal 2019.

Meanwhile, the most recent budget deficit under Biden was about $1.7 trillion in fiscal 2023. As of June, the nonpartisan Congressional Budget Office  projected  that the deficit for fiscal 2024, which ends on Sept. 30, would be about $2 trillion.

Black Unemployment

Biden boasted that on his watch, “Black unemployment is the lowest level it has been in a long, long time.”

It’s true that the unemployment rate for Black or African American people reached a record low of 4.8% in April 2023, but it is currently 6.1%,  according to  the Bureau of Labor Statistics, which has data going back to 1972.

Also, the unemployment rate was low under Trump, too, until the pandemic.

Under Trump, the  unemployment rate for Black Americans  went down to 5.3% in August 2019 – the lowest on record at that time. It shot up to 16.9% in April 2020, when the economic effects of the pandemic took hold. When Trump left office in January 2021, amid the pandemic, the rate was 9.3%.

The rate has been 6% or less in only 29 months since 1972, and it happened only under two presidents: 21 times under Biden and eight times under Trump.

‘Suckers and Losers’

Biden  said  Trump called U.S. veterans killed in World War I “suckers and losers,” which Trump called a “made up quote … that was in a third-rate magazine.”

It was first reported by a magazine — the Atlantic — but Trump’s former chief of staff,  John F. Kelly , a retired four-star Marine general, later seemed to confirm it.

Biden was referring to a trip Trump made to France in November 2018, where he reportedly declined to visit the  Aisne-Marne American Cemetery  near the location of the Battle of Belleau Wood. “He was standing with his four-star general and he told him, ‘I don’t want to go in there because they’re a bunch of losers and suckers.’”

The Atlantic  wrote  about this alleged incident in 2020, citing unnamed sources. The magazine wrote that Trump made his remark about “losers” when he declined to visit the Aisne-Marne American Cemetery, and his remark about “suckers” during that same trip.

The Atlantic, Sept. 3, 2020:  In a conversation with senior staff members on the morning of the scheduled visit, Trump said, “Why should I go to that cemetery? It’s filled with losers.” In a separate conversation on the same trip, Trump referred to the more than 1,800 marines who lost their lives at Belleau Wood as “suckers” for getting killed.

In October 2023, Kelly – who was on that trip and visited the Aisne-Marne Cemetery — gave a  statement to CNN  that seemed to confirm those remarks. CNN published Kelly’s statement.

CNN, Oct. 3, 2023:  “What can I add that has not already been said?” Kelly said, when asked if he wanted to weigh in on his former boss in light of recent comments made by other former Trump officials. “A person that thinks those who defend their country in uniform, or are shot down or seriously wounded in combat, or spend years being tortured as POWs are all ‘suckers’ because ‘there is nothing in it for them.’ A person that did not want to be seen in the presence of military amputees because ‘it doesn’t look good for me.’ A person who demonstrated open contempt for a Gold Star family – for all Gold Star families – on TV during the 2016 campaign, and rants that our most precious heroes who gave their lives in America’s defense are ‘losers’ and wouldn’t visit their graves in France.”

Trump said, “We had 19 people who said I didn’t say it.” One of those who said that he didn’t hear Trump make those remarks is John Bolton, Trump’s former national security adviser who was also on the trip and said he was there when the decision was made not to visit the cemetery.

“I didn’t hear that,” Bolton  told the New York Times  in 2020 after the magazine story first appeared. “I’m not saying he didn’t say them later in the day or another time, but I was there for that discussion.”

Biden Misleads on Jobs

Biden ignored the economic impact of the COVID-19 pandemic when he criticized Trump for employment going down over Trump’s time in office.

“He’s the only president other than Herbert Hoover that lost more jobs than he had when he began,” Biden said.

Job growth during Trump’s term was positive until the economy lost 20.5 million jobs in April 2020, as efforts to slow the spread of the novel coronavirus led to business closures and layoffs. By the time Trump left office in January 2021, employment had partly rebounded, but was still 9.4 million jobs below the February 2020 peak,  according to the Bureau of Labor Statistics .

Trump repeatedly claimed that Biden “caused the inflation” and that “I gave him a country with no essentially no inflation. It was perfect. It was so good.”

It’s true that inflation was relatively modest when Trump was president. The  Consumer Price Index rose 7.6%  under Trump’s four years — continuing a long period of low inflation. And inflation has been high over the entirety of Biden’s time in office. The  Consumer Price Index  for all items rose 19.3% between January 2021 and May.

For a time, it was the worst inflation in decades. The 12 months ending in June 2022 saw a 9% increase in the CPI (before seasonal adjustment), which the  Bureau of Labor Statistics said  was the biggest such increase since the 12 months ending in November 1981.

Inflation has moderated more recently. The CPI  rose  3.3% in the 12 months ending in May, the most recent figure available.

Although Trump claims that Biden is entirely responsible for massive inflation, economists  we have spoken to  say Biden’s policies are only partly to blame. The economists placed the lion’s share of the blame for inflation on disruptions to the economy caused by the pandemic, including supply shortages, labor issues and increased consumer spending on goods. Inflation was then worsened by Russia’s attack on Ukraine, which drove up oil and gas prices, experts told us.

Indeed, inflation has been a  worldwide problem  post-pandemic.

However, many economists say Biden’s policies — particularly aggressive stimulus spending early in his presidency to offset some of the economic damage caused by the pandemic — played a modest role.

Jason Furman , a former economic adviser to President Barack Obama and now a Harvard University professor, told us in June 2022 that he estimated about 1 to 4 percentage points worth of the inflation was due to Biden’s stimulus spending in the  American Rescue Plan  — a $1.9 trillion pandemic relief measure that included $1,400 checks to most Americans; expanded unemployment benefits; and money for schools, small businesses and states.  Mark Zandi , chief economist of Moody’s — whose work is often cited by the White House — said the impact of the stimulus measure now “has largely faded.”

Economists note that the American Rescue Plan came after two other pandemic stimulus laws enacted under Trump that were  worth  a  total  of $3.1 trillion. That spending, too, could have contributed to inflation.

Immigrants Entering U.S. Under Biden

Trump grossly inflated the number of immigrants who have entered the country during the Biden administration — putting the number at 18 million to 20 million. The number, by our calculation, is about a third of that. Trump also claimed, without evidence, that many of those immigrants are from prisons and mental institutions.

“It could be 18, it could be 19, and even 20 million people,” Trump said of the immigrants who have entered the U.S. during the Biden administration. Later in the debate, Trump asked Biden why there had been no accountability “for allowing 18 million people many from prisons, many from mental institutions” into the country.

That’s a greatly exaggerated number. We took a deep dive into the immigration numbers  in February , and again in  mid-June , and we came up with an estimate of at most a third of Trump’s number.

Here’s the breakdown:

Department of Homeland Security data show nearly 8 million encounters at the U.S.-Mexico border between February 2021, the month after Biden took office, and May, the last month of available  statistics . That’s a figure that includes both the 6.9 million apprehensions of migrants caught between legal ports of entry – the number typically used for illegal immigration – and nearly 1.1 million encounters of migrants who arrived at ports of entry without authorization to enter the U.S.

DHS also has comprehensive data, through February, of the initial processing of these encounters. That information shows 2.9 million were removed by Customs and Border Protection and 3.2 million were released with notices to appear in immigration court or report to Immigration and Customs Enforcement in the future, or other classifications, such as parole. (Encounters do not represent the total number of people, because some people attempt multiple crossings. For example, the recidivism rate was 27% in fiscal year 2021,  according to the most recent figures  from CBP.) 

As  we’ve explained before , there are also estimates for “gotaways,” or migrants who crossed the border illegally and evaded the authorities. Based on an average annual apprehension rate of 78%, which DHS provided to us, that would mean there were an estimated 1.8 million gotaways from February 2021 to February 2024. The gotaways plus those released with court notices or other designations would total about 5 million.

There were also 407,500 transfers of unaccompanied children to the Department of Health and Human Services and 883,000 transfers to ICE. The ICE transfers include those who are then booked into ICE custody, enrolled in “ alternatives to detention ” (which include technological monitoring) or released by ICE. We don’t know how many of those were released into the country with a court notice. But even if we include those figures, it still doesn’t get us to anywhere near 18 to 20 million.

And we should note that these figures do not reflect whether a migrant may ultimately be allowed to stay or will be deported, particularly since there is a yearslong backlog of immigration court cases.

Also, as we have  written   repeatedly , Trump has provided no credible support for his incendiary claim that countries are emptying their prisons and mental institutions and sending those people to the U.S. Experts tell us they have seen no evidence to substantiate it.

Earlier this month, we looked into  Trump’s claim as it relates to Venezuela, because Trump has repeatedly cited a drop in crime there to support his claim about countries emptying their prisons and sending inmates to the U.S. Reported crime is trending down in Venezuela, but crime experts in the country say there are numerous reasons for that — including an enormous out-migration of citizens and a consolidation of gang activity — and they have nothing to do with sending criminals to the U.S.

“We have no evidence that the Venezuelan government is emptying the prisons or mental hospitals to send them out of the country, whether to the USA or any other country,” Roberto Briceño-León, founder and director of the independent Venezuelan Observatory of Violence, told us.

Border Under Trump

Trump claimed that “we had the safest border in history” in the “final months” of his presidency, according to Border Patrol. But according to  data  provided by Customs and Border Protection, apprehensions of those trying to cross illegally into the U.S. in the last three full months of Trump’s presidency were about 50% higher than in the  three months  before he took office.

In fact, as we wrote in our piece, “ Trump’s Final Numbers ,” illegal border crossings, as measured by  apprehensions at the southwest border , were 14.7% higher in Trump’s final year in office compared with the last full year before he was sworn in.

But these statistics tell only part of the story. The number of apprehensions fluctuated wildly during Trump’s presidency, from a  monthly  low of 11,127 in April 2017 to a high of 132,856 in May 2019.

Back in April,  we wrote  about a misleading chart that Trump showed to the crowd during a speech in Green Bay, Wisconsin. “See the arrow on the bottom? That was my last week in office,” Trump said. “That was the lowest number in history.” But Trump was wrong on both points.

The arrow was pointing to apprehensions in April 2020, when apprehensions plummeted during the height of the pandemic.

“The pandemic was responsible for a near-complete halt to all forms of global mobility in 2020, due to a combination of border restrictions imposed by countries around the world,”  Michelle Mittelstadt , director of communications for the Migration Policy Institute, told us.

After apprehensions reached a pandemic low in April 2020, they rose every month after that. In his last months in office, apprehensions had more than quadrupled from that pandemic low and were higher than the month he took office.

Trump falsely claimed that “some states” run by Democrats allow abortions “after birth.” As  we have written , that’s simply false. If it happened, it would be  homicide , and that’s  illegal .

“No such procedure exists,” the American College of Obstetricians and Gynecologists  says  on its website.

The former president  has wrongly said  that abortions after birth were permitted under Roe v. Wade — the Supreme Court ruling that established a constitutional right to abortion until it was  reversed  in 2022. It was not.

Under Roe, states could outlaw abortion after fetal viability, but with exceptions for risks to the life or health of the mother. Many Republicans  have objected  to the health stipulation, saying it would allow abortion for any reason. Democrats say exceptions are needed to protect the mother from medical risks. We should note, late-term abortions  are rare . According to the  Centers for Disease Control and Prevention , less than 1% of abortions in the U.S. in 2020 were performed after 21 weeks gestational time.

In June 2022, after Trump had appointed three conservative justices to the Supreme Court, the court  overturned  Roe in a 5-4 ruling. Biden  supports  restoring Roe as “the law of the land,” as he said in his State of the Union address in March.

Trump Calls Border ‘The Most Dangerous Place’

In his focus on the U.S. border with Mexico, Trump  made  the unsupported claim that it is “the most dangerous place in the world.”

It’s true that unauthorized border crossings  can be dangerous  — 895 people died while doing so in fiscal year 2022, which is the most recent year for which the Customs and Border Protection has  data . Most of those deaths were heat related.

And the International Organization for Migration called calendar year 2022 “the deadliest year on record” for migration in the Americas, with a total of 1,457 fatalities throughout South America, Central America, North America and the Caribbean. The organization began tracking deaths and disappearances related to migration in 2014.

“Most of these fatalities are related to the lack of options for safe and regular mobility, which increases the likelihood that people see no other choice but to opt for irregular migration routes that put their lives at risk,” the organization said in its  2022 report .

Trump suggested that the border crossings imperil Americans when he went on to say, “these killers are coming into our country, and they are raping and killing women.”

But, as  we’ve written before , FBI data show a downward trend in violent crime in the U.S., and there’s no evidence to support the claim that there’s been a crime wave driven by immigrants.

Crime analyst Jeff Asher, co-founder of the New Orleans firm  AH Datalytics , told us in May that there’s no evidence in the data to indicate a migrant crime wave.

Similarly, Jeffrey Butts, director of the Research and Evaluation Center at the John Jay College of Criminal Justice,  told the New York Times  in February there was no evidence of a migrant crime wave in New York City after Texas Gov. Greg Abbott began busing migrants there in April 2022.

“I would interpret a ‘wave’ to mean something significant, meaningful and a departure from the norm,” Butts said at the time. “So far, what we have are individual incidents of crime.”

Also, it’s worth noting that the Institute for Economics and Peace’s  Global Peace Index  — which measures the safety of 163 countries based on 23 indicators, including violent crime, deaths from internal conflict and terrorism — said the “least peaceful country” is Afghanistan, followed by Yemen, Syria, South Sudan and the Democratic Republic of the Congo.

In discussing inflation, the former president embellished the degree to which food prices have increased.

“It’s killing people. They can’t buy groceries anymore,” Trump said. “You look at the cost of food, where it’s doubled, tripled and quadrupled. They can’t live.”

According to the Bureau of Labor Statistics, the Consumer Price Index for food has  gone up 17.5%  — not 100% to 300% — since January 2021. The Consumer Price Index specifically for groceries, or “food at home,” has  risen 20.8% .

Climate Change

During a short exchange about climate change, Trump boasted that during his tenure “we had the best environmental numbers ever.” It is not clear what he was referring to exactly, but he said if elected president he wanted to have “absolutely immaculate clean water and I want absolutely clean air — and we had it.” He might have been referring to a talking point that Andrew Wheeler, Trump’s former Environmental Protection Agency administrator, had recommended Trump mention during the debate: “CO2 emissions went down” during his administration, as  the Hill reported . 

Greenhouse gas emissions, which are responsible for global warming,  did decline  from 2019 to 2020. But that was “largely due to the impacts of the coronavirus (COVID-19) pandemic on travel and economic activity,” according to the EPA. Emissions increased by 5.7% from 2020 to 2022, once the economy started getting reactivated again, the agency said. 

According to an  analysis by the New York Times , Trump’s administration reversed nearly 100 environmental rules, including 28 regulations on air pollution and emissions, and eight rules that limited water pollution. Reportedly, Trump  recently asked  oil executives and lobbyists to donate to his campaign, promising he would roll back other environmental rules that hurt fossil fuel interests. 

“He’s not done a damn thing for the environment,” Biden said in response, pointing out that Trump had  pulled the U.S. out of the Paris Agreement . “I immediately joined it because if we reach the 1.5 degrees Celsius … there’s no way back,” Biden said. 

As  we’ve reported , although reaching 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, of warming comes with a number of very serious impacts, it is not a point of no return. Scientists agree that every increment of global warming increases these negative impacts, but 1.5 degrees is not a magic number after which everything is doomed, they say. 

Immigrants Living in Hotels

During the debate, Trump  mentioned   twice  that while immigrants crossing the border illegally were “living in luxury hotels,” in New York City and other cities “our veterans are living in the street.”

While it is true that New York City has  provided   hotel   rooms  to migrant families as a temporary shelter solution, there is no evidence that immigrants are being placed in “luxury” hotels. 

In 2023, Mayor Eric Adams  signed  a $275 million contract with the Hotel Association of New York City to house 5,000 migrants. The deal was intended to help  struggling hotels  impacted by the pandemic and did not expect to include luxury hotels. “There are no gold-plated rooms that are being given away contrary to any reports that you may have seen,” the association president  told NY1  at the time. In January, the city  signed  another $77 million contract to shelter migrant families in hotels. 

In April, social media posts falsely claimed immigrants had stormed New York City Hall to demand luxury hotel accommodations. But as the  Associated Press reported , the immigrants were there for a hearing about racial inequities in shelter and immigrant services. 

In 2023, the number of veterans experiencing homelessness increased 7.4% from 2022, according to  data  from the Department of Housing and Urban Development. But homelessness among veterans has been declining in recent years, with a 4% overall reduction within the last three years alone. 

Terrorist Attacks Under Trump

While talking about Iran and terrorism, Trump falsely claimed that “you had no terror, at all, during my administration.” As  we’ve written , there were several acts of terrorism carried out by foreign-born individuals when Trump was in office.

For example, in October 2017, Sayfullo Saipov  used  a truck to run down people in New York City. He killed eight people,  including  Americans and tourists, in an attack carried out on behalf of the Islamic State.

Then in December 2017, Akayed Ullah  detonated  a homemade pipe bomb he was wearing inside a New York City subway station. Ullah  told  authorities he did it in response to U.S. airstrikes against the Islamic State in Syria and other places.

Then in  December 2019 , Second Lt. Mohammed Saeed Alshamrani, a member of the Royal Saudi Air Force, shot 11 people at Florida’s Naval Air Station Pensacola, killing three U.S. sailors. Trump’s own attorney general, William Barr,  called  it an act of terrorism in January 2020. “The evidence shows that the shooter was motivated by jihadist ideology,” Barr said in a statement.

China Trade Deficit

When discussing U.S. trade relations with China, Trump said “we have the largest deficit with China.” That’s false, as  we’ve written .

In 2023, the U.S. had a trade deficit with China in goods and services of roughly $252 billion,  according to  revised figures the Bureau of Economic Analysis  released  in early June. The deficit in goods trading was about $279 billion which was partially offset by a roughly $27 billion surplus in the trading of  services  — which can include travel, transportation, finance and intellectual property.

The trade gap with China last year was the lowest it had been since 2009, when it was $220 billion.

In fact, according to BEA data going back to 1999, the highest total U.S.-China trade deficit in goods and services was about $378 billion in 2018 — when Trump was president. Under Biden, the highest trade deficit with China was $366 billion in 2022.

Not ‘Greatest Economy’ Under Trump

Trump falsely said that prior to the pandemic, the U.S. had “the greatest economy in the history of our country. … Everything was locked in good.”

Trump’s boast about creating the “greatest economy in history” is ubiquitous in his campaign speeches. And it’s not true, at least not by the objective measure typically used to gauge the health of the economy.

As  we have written , economists generally measure a nation’s health by the growth of its  inflation-adjusted gross domestic product . Under Trump, growth was modest. Real GDP in Trump’s four years grew annually by 2.5% in 2017, 3% in 2018 and 2.5% in 2019 — before the economy went into a tailspin during the pandemic in 2020, when real GDP declined by 2.2%,  according to  the Bureau of Economic Analysis.

So, in the best year under Trump, U.S. real GDP grew annually by 3%. By contrast, the nation’s economy grew at a faster annual rate  48 times  and under every president before and after Trump dating to 1930, except Barack Obama and Herbert Hoover. The economy grew at more than 3% six of Ronald Reagan’s eight years, including 7.2% in 1984, and it grew 5% or more 10 times under Franklin D. Roosevelt, including 18.9% in 1942.  Under Biden , the GDP grew by 5.8% in 2021 — a post COVID-19 bounce-back — by 1.9% in 2022 and 2.5% in 2023.

Trump’s Was Not Largest Tax Cut in History

As he has many times before, Trump wrongly claimed, “I gave you the largest tax cut in history.” But saying this over and over, as Trump has for years, doesn’t make it any more true.

As  we have been writing  even before the 2017  Tax Cuts and Jobs Act  was enacted into law, while the law provided tax relief to nearly all Americans, it was not the largest tax cut in U.S. history either as a percentage of gross domestic product (the measure preferred by economists) or in inflation-adjusted dollars.

According to a Tax Policy Center  analysis , the law reduced the individual income taxes owed by Americans by about $1,260 on average in 2018. It also reduced the top corporate tax rate from  35% to 21% , beginning in January 2018.

The law signed by Trump was initially projected to cost $1.49 trillion over 10 years,  according to the nonpartisan Joint Committee on Taxation . It could end up costing substantially more if individual tax provisions are extended past 2025. Over the first four years, the average annual cost was estimated to be $185 billion. That was about 0.9% of  gross domestic product  in 2018.

That’s nowhere close to President Ronald Reagan’s 1981 tax cut, which was 2.89% of GDP over a four-year average. That’s according to a  2013 Treasury Department analysis  on the revenue effects of major tax legislation. Five more tax measures since 1940 had an impact larger than 1% of GDP, and the Committee for a Responsible Federal Budget  includes  a 1921 measure as also being larger than the 2017 plan. That’s eighth place for Trump’s “biggest tax cut in our history.”

In inflation-adjusted dollars, the Trump-era tax cut is also less than the American Taxpayer Relief Act of 2012, which comes in at No. 1 with a $320.6 billion cost over a four-year average. And it’s less than tax reductions in 2010 ($210 billion) and 1981 ($208 billion).
