Vice President Kamala Harris and former President Donald Trump met for the first time Tuesday in their first presidential debate of the 2024 election, hosted by ABC News.

The high-stakes, 90-minute debate was held at Philadelphia's National Constitution Center, with Trump and Harris arguing their case for the White House.

As the Democratic and Republican nominees debated the most pressing topics facing the nation, ABC News live fact-checked their statements for answers that were exaggerated, needed more context or were false.

HARRIS CLAIM: 16 Nobel laureates say Trump's plan would increase inflation and land us in a recession

FACT-CHECK: Mostly true

Harris correctly describes what the Nobel laureates said about inflation during Trump's presidency: "There is rightly a worry that Donald Trump will reignite this inflation." But while the group describes Harris' agenda as "vastly superior" to Trump's, their letter doesn't specifically predict a recession by the middle of 2025. Rather, the group wrote: "We believe that a second Trump term would have a negative impact on the U.S.'s economic standing in the world and a destabilizing effect on the U.S.'s domestic economy."

The 16 economists are George Akerlof, Angus Deaton, Claudia Goldin, Oliver Hart, Eric S. Maskin, Daniel L. McFadden, Paul R. Milgrom, Roger B. Myerson, Edmund S. Phelps, Paul M. Romer, Alvin E. Roth, William F. Sharp, Robert J. Shiller, Christopher A. Sims, Joseph Stiglitz and Robert B. Wilson.

HARRIS CLAIM: Trump wants a "20% tax on everyday goods" that would cost families "about $4,000 more a year."

FACT-CHECK: True, but needs context

Trump has proposed a universal "10-20%" tariff on all U.S. imports, from cars and electronics to wine, food products and many other goods. He has also proposed a 60% tariff on imports from China. Vice President Harris called the plan "Trump's sales tax," though the former president has not explicitly proposed such a tax. Independent economists, however, say the proposed import tariffs would unquestionably result in higher prices for American consumers across the board.

The precise financial impact on families is hard to predict and estimates vary widely -- from additional annual costs per household of $1,700 to nearly $4,000, depending on the study. Trump has not called for any tax hikes for American families.

He has proposed exempting Social Security benefits and tips from taxation, as well as extending individual tax cuts enacted in 2017.

TRUMP CLAIM: Trump said, "We have inflation like very few people have ever seen before. Probably the worst in our nation's history."

FACT-CHECK: False, but it was very high

It's true that early in Joe Biden's presidency the annual inflation rate peaked at roughly 9% (June of 2022), but that's not the highest it's ever been. There are several examples of the inflation rate being much higher than 9% in the U.S, including in the immediate aftermath of World War II and during the oil embargo and shortages of the late '70s and early 1980s, when the inflation rate peaked at 14.5%.

The inflation rate as of July 2024 is at 2.9% annual inflation, the lowest it has been in three years. It should also be noted that President Biden has falsely claimed that he inherited a high rate from his predecessor. In fact, inflation was at 1.4% when he took office.

*Data for this fact check was gathered from Federal Reserve Bank of St. Louis, or St. Louis Fed

HARRIS CLAIM: Harris said, "Trump left us the worst unemployment since the Great Depression."

FACT-CHECK: Needs context

The unemployment rate peaked at 14.8% in April 2020 when Trump was in office – that was indeed the highest level since the Great Depression, according to the Bureau of Labor Statistics. But unemployment rapidly declined to 6.4% in January 2021 by the time Trump left office, as the economy started to rebalance. And that 6.4% unemployment rate is still better than the 10% peak during the Great Recession in October 2009.

If you eliminate pandemic statistics, the lowest unemployment rate under Trump was just slightly higher than the lowest point under Biden. Both were good: 3.5% under Trump and 3.4% under Biden at their lowest respectively, according to data provided by the Federal Reserve Bank of St. Louis and Bureau of Labor Statistics.

HARRIS CLAIM: Trump "killed" bill that would have secured border

FACT-CHECK: True

Earlier this year, a bipartisan group of senators unveiled a $20 billion plan to substantially bolster security along the U.S.-Mexico border. It would have added hundreds of border patrol and ICE agents and asylum officers; funded construction of a new border wall; expanded detention facilities; ended "catch and release;" effectively closed the border entirely when illegal crossings surge; and raised the bar for asylum claims, according to the bill.

The influential Border Patrol union, which has previously endorsed Trump, publicly backed the bill. But hours after the draft legislation was unveiled on Feb. 5, Trump urged his party to oppose the bill, even as many Republicans have spent years lobbying for some of the security measures included in the deal.

"I'll fight it all the way," Trump told supporters at a Las Vegas rally on Feb. 8. "A lot of the senators are trying to say, respectfully, they're blaming it on me. I say, that's okay. Please blame it on me." Trump openly invoked election-year politics as a motivation for his position: "This Bill is a great gift to the Democrats, and a Death Wish for The Republican Party. It takes the HORRIBLE JOB the Democrats have done on Immigration and the Border, absolves them, and puts it all squarely on the shoulders of Republicans," Trump wrote on social media. The bill failed a key Senate procedural vote in May, with all but one Republican voting against it, including all those involved in crafting the deal.

TRUMP CLAIM: Haitian migrants eating pets in Ohio

Fact Check: False

According to the city of Springfield, Ohio, these claims are false. A city spokesperson tells ABC News there have been "no credible reports or specific claims of pets being harmed, injured or abused by individuals in the immigrant community."

Rumors that migrants from Haiti are stealing and eating animals there have run rampant after a series of claims spread widely online, amplified by social media posts from leading political figures in recent days.

"Additionally, there have been no verified instances of immigrants engaging in illegal activities such as squatting or littering in front of residents' homes. Furthermore, no reports have been made regarding members of the immigrant community deliberately disrupting traffic," the spokesperson added.

The House Judiciary GOP X account used AI tools to show Trump holding cats and ducks, portraying him as a savior of animals.

One of the main images circulating online, showing a man holding a dead goose, was taken not in Springfield but in Columbus, Ohio, two months ago. The resident who captured the image told ABC News he was surprised to see his image used to " push false narratives."

According to the Springfield News-Sun, the Springfield Police Department has not received any reports of pets being stolen and eaten. The city even created a webpage debunking some claims.

Migrants have been drawn to the region because of low cost of living and work opportunities, the city says on its site. The city estimates there are around 12,000 to 15,000 immigrants living in the county, and that the rapid rise in population has strained housing, health care, and school resources. But the city also says that the migrants are in the country legally and that many are recipients of Temporary Protected Status from the federal government.

HARRIS CLAIM: Trump 'intends on implementing' Project 2025

FACT-CHECK: Needs context

Conservative allies and former advisers to Donald Trump published a 900-page policy blueprint in April 2023 to help a new Republican administration transition to power. The effort – dubbed Project 2025 – was organized by the Heritage Foundation, a prominent right-wing think tank. It details proposals for staffing the government and restructuring federal agencies, writing regulations, managing the economy and ensuring national security.

Harris claims Trump "intends on implementing" the "detailed and dangerous" plan if he wins a second term. But Trump denies any association with Project 2025, saying on social media in July: "I have not seen it, have no idea who is in charge of it," and also publicly denounced its substance as "seriously extreme" and developed by the "severe right."

"I disagree with some of the things they're saying and some of the things they're saying are absolutely ridiculous and abysmal," Trump posted on social media. Many of the document's priorities, however, are broadly championed by Trump, including construction of a border wall, mass deportation of undocumented immigrants and banning transgender athletes from women's sports, among other things.

Dozens of former members of his administration were involved in the project, including former cabinet secretaries and West Wing aides. Many of the same people helped craft the Republican Party platform, ABC News has reported. Speaking at a Heritage Foundation event in April 2022, Trump said: "This is a great group and they're going to lay the groundwork and detail plans for exactly what our movement will do... when the American people give us a colossal mandate to save America."

HARRIS CLAIM: Harris said, 'If Donald Trump were to be reelected, he will sign a national abortion ban.'

FACT-CHECK: False

Trump has said he has "no regrets" in selecting the Supreme Court justices who overturned the constitutional right to an abortion. But he also repeatedly has promised that if elected, he will not sign a federal abortion ban into law and will leave the issue up to the states. One open question this year had been whether he would enforce the Comstock Act, an 1873 law that prohibits mailing materials used in abortions.

Among other things, the law would make it illegal to ship the drug mifepristone, which is used to terminate early pregnancies. The Biden administration has said the law is unenforceable because the drug has medical uses other than abortion, and it would be impossible to know how the drug was being used. Trump's running mate, JD Vance, and other conservatives have called for the enforcement of the law.

In an August interview with CBS News, Trump said that while "we will be discussing specifics of it," he will not enforce the Comstock Act.

TRUMP CLAIM: Trump said, 'They didn't fire anybody having to do with Afghanistan.'

FACT-CHECK: True, but needs context.

It is accurate that no one with a direct role in the chaotic withdrawal of U.S. troops from Afghanistan in 2021 has been held publicly accountable.

Trump appears to be specifically referring to a suicide bombing that killed 13 U.S. service members. U.S. Central Command ultimately concluded that the bombing was not preventable and that members of a Marine sniper team were mistaken when they told others they had the suicide bomber in their sights.

Trump, congressional Republicans and several Gold Star families say they believe these investigations have not gone far enough.

TRUMP CLAIM: Kamala Harris wants to ban fracking

FACT-CHECK: Needs context

It's true that Harris once called to ban fracking altogether, but she has since said she changed her policy view. During a CNN town hall on climate change in 2019 when she was still a Senator, Harris said, "There's no question I'm in favor of banning fracking." Fracking is short for "hydraulic fracturing," and it's a technique used in the extraction of oil and natural gas from underground rock formations.

Harris also said she backed California's efforts to stop the practice in her home state when she was the state's attorney general. However, she eventually changed her view on fracking when she became Biden's running mate in 2020. During an October 2020 segment on ABC's The View, Harris said neither she nor Biden would ban fracking. Harris reiterated that she would not ban fracking during the ABC News Presidential Debate.

TRUMP CLAIM: Trump said, 'I'd like to give you 10,000 National Guard soldiers. They rejected me. Nancy [Pelosi] rejected me.'

FACT-CHECK: False

The final report by the bipartisan Select Committee to Investigate the January 6th Attack on the United States Capitol determined there was "no evidence" to support the claim that Trump gave an order "to have 10,000 troops ready for January 6th."

The report quoted President Trump's Acting Secretary of Defense Christopher Miller, who directly refuted this claim under oath, saying, "There was no direct order from the President" to put 10,000 troops to be on the ready for Jan. 6.

Instead, the report noted that when Trump referenced that number of troops, it was not to protect the Capitol but that he had "floated the idea of having 10,000 National Guardsmen deployed to protect him and his supporters from any supposed threats by left-wing counter-protesters."

HARRIS CLAIM: If elected, Trump would be immune from criminal prosecution

FACT-CHECK: Partly true

Vice President Harris claimed Trump would be "immune from any misconduct" and have "no guard rails" after a landmark Supreme Court decision in June.

The court did rule that presidents and former presidents “may not be prosecuted for exercising his core constitutional powers.” (Article II of the Constitution lists the core powers, which include the ability to make treaties, veto bills, nominate cabinet members, appoint ambassadors, act as Commander-in-Chief of the military, and grant pardons.) The court also said that presidents enjoy "at least presumptive immunity" for other "official acts" – defined broadly as actions within the "outer perimeter" of official responsibilities but not "manifestly or palpably beyond his authority."

While the decision is widely construed as granting broad protection for a president, the court said presidents are "not above the law" and enjoy no "absolute" immunity, leaving room for a narrow set of cases where a current or former president could face criminal prosecution. There is also no immunity for "unofficial" acts, the court said.

Trump faces a pair of active federal criminal cases against him brought by Special Counsel Jack Smith. The Supreme Court decision does not mean those prosecutions cannot move forward, but it has significantly delayed proceedings and made it more difficult to convict Trump. If he were to win a second term, Trump's Justice Department could dismiss the Special Counsel and effectively end the cases against him.

TRUMP CLAIM: Trump said he ended the Nord Stream 2 pipeline, and 'Biden put it back on day one.'

FACT-CHECK: Mostly false

The Nord Stream 2 is an undersea pipeline that would have allowed Russia to increase natural gas exports to Western Europe while bypassing Ukraine and depriving Kyiv billions of dollars in access fees. It's true that in 2019, Trump announced sanctions that halted the pipeline's construction. But by that point, the pipeline was nearly complete with a majority of the project occurring under Trump's presidency, according to a 2020 analysis by the Congressional Research Service.

Biden later waived sanctions against the pipeline's builder at the request of Germany in 2021, but reimposed penalties the following year as Russia invaded Ukraine.

HARRIS CLAIM: Trump's deal with the Taliban is to blame for the chaotic withdrawal in Afghanistan.

FACT-CHECK: Needs context

The top government watchdog on the Afghanistan war blames Trump's 2020 deal with the Taliban as "the single most important factor" in the rapid collapse of Afghanistan's forces a year later. But the same office also says Biden's decision to stick with a firm withdrawal date of U.S. troops was a factor as well.

Trump's deal with the Taliban called for the withdrawal of U.S. forces by May 2021 and release 5,000 of its fighters from Afghan prisons so long as they agreed not to attack U.S. forces. According to the Special Inspector General for Afghanistan Reconstruction, the agreement was seen by Afghan forces as a "signal that the U.S. was handing over Afghanistan to the enemy as it rushed to exit the country." Trump also had reduced U.S. troop levels to the lowest point in the 20-year war, and Afghan forces weren't prepared to take over, according to the inspector general.

Biden aides say the poor security situation when he took office in January 2021 put the newly elected president in an almost impossible position. Biden could have surged U.S. troops to the country to try to bolster the weakened Afghan government. But doing so would have extended what was already the nation's longest war and put American forces at risk of renewed attacks by the Taliban. According to the inspector general, Biden's announcement that he would stick with a 2021 withdrawal date contributed to the poor morale among Afghan troops, paving the way for a government collapse and subsequent Taliban takeover.

TRUMP CLAIM: Harris and Walz support abortion 'in the seventh month, the eighth month, the ninth month… And probably after birth.'

FACT-CHECK: False

Trump has claimed that Democrats in some states allow for the killing of an infant after birth. This is false.

There is no state that allows the killing of a baby after birth. Infanticide is illegal in all 50 states. His false claim stems from a refusal by many Democrats to support any legal restrictions on abortion, and he specifically references comments by former Virginia Gov. Ralph Northam, a physician, who once said that in rare, late-pregnancy cases when fetuses are nonviable, doctors deliver the baby, resuscitate it if the mother wishes, and then have a "discussion" with the mother.

While most states that allow abortion do so only up until fetal viability, there are several states – including Colorado, New Jersey, New Mexico, Oregon, Vermont and Gov. Tim Walz's home state of Minnesota — that do not impose a legal limit on abortion procedures. Advocates for abortion rights say the absence of legal consequences after fetal liability doesn't mean doctors will try to terminate full-term, healthy pregnancies.

In fact, access to late-term procedures is limited, costly and medically complex -- typically done only when a woman's life is threatened or the fetus isn't expected to survive. Many Democrats say they want to pass legislation that would codify the 1973 Supreme Court decision Roe v. Wade, which protects abortion rights up until viability.

TRUMP CLAIM: Trump said he lost the 2020 election on a 'technicality' because judges determined he lacked standing in election lawsuits.

FACT-CHECK: False

Trump lost the 2020 election after Biden won 306 electoral votes, compared to Trump's 232 electoral votes.

After losing the 2020 election, Trump and his allies filed more than 60 lawsuits to challenge the outcome of the election -- the overwhelming majority of which were dismissed or dropped. Many of the cases were dismissed because the plaintiffs in the cases could not prove a strong enough connection to the action they were challenging. Not having "standing" is a common and legally justifiable reason for a case to be dismissed.

TRUMP CLAIM: The Biden administration left $85 billion worth of 'brand new beautiful military equipment behind' in Afghanistan that was seized by the Taliban.

FACT-CHECK: False

This is not accurate, as $83 billion is an estimate of the entire amount spent by the US in security assistance in Afghanistan since 2001.

Still, the Defense Department's Inspector General estimates $7.12 billion worth of U.S.-funded equipment was seized by the Taliban when the U.S. withdrew. According to the government watchdog, that amount includes 78 aircraft, some 9,500 air-to-ground munitions, 40,000 vehicles, 300,000 weapons and nearly all night-vision, surveillance, communications and biometric equipment provided to Afghanistan forces.

HARRIS CLAIM: Harris said of the Central Park 5, 'Trump took out a full-page ad calling for their execution'

FACT-CHECK: True

Not long after the Central Park Five were arrested, Trump placed full-page ads in New York newspapers urging New York to bring back the death penalty. "These muggers and murderers" should be "forced to suffer and, when they kill, they should be executed for their crimes," said the ad, above Trump's signature.

HARRIS CLAIM: Trump exchanged love letters with Kim Jong Un

FACT-CHECK: False

Trump did exchange letters with Kim Jong Un in August 2018 after the two leaders held a summit together in Singapore in June 2018. Trump tweeted thanking the North Korean leader "for your nice letter – I look forward to seeing you soon." The White House at the time said Trump sent a reply to the North Korean leader, but the White House did not provide details about what was in Kim Jong Un's letter or what was in Trump's reply.

In August 2019, Trump said he received a "very beautiful letter" from North Korean leader Kim Jong Un when speaking to reporters.

In September 2018, Trump told a crowd at a campaign rally that there was once tough talk between the two leaders, "and then we fell in love."

"And then we fell in love, okay? No, really - he wrote me beautiful letters, and they're great letters," Trump said at the rally. Trump did often speak favorably of North Korean leader Kim Jong Un during and after his presidency.

HARRIS CLAIM: Biden-Harris made historic investments in clean energy

FACT-CHECK: Needs context

The U.S. budget for clean energy investments (over $559 billion as of August 2023) is the largest in the world, according to the World Economic Forum. About a third of that investment is going toward low-carbon electricity projects, and about a quarter is aimed at developing low-carbon, efficient transportation, according to WEF. In the first quarter of 2024, the U.S. "continued its record-setting growth" with a new high of $71 billion invested in clean energy and transportation, according to Clean Investment Monitor.

At the same time, the U.S. Energy Information Administration reported in March that the U.S. is now producing more crude oil than any country ever has -- and has been for the past six years in a row. In December 2023 the U.S. reached a new monthly record high of more than 13.3 million barrels per day, according to the EIA.

The Harris-Walz campaign told ABC News that the trillion-dollar amount cited by the vice president is based on the total spending of the Inflation Reduction Act, the CHIPS and Science Act of 2022 and the Bipartisan Infrastructure Law. In a statement, they told us "Vice President Harris was proud to cast the tie-breaking vote on the largest ever investment to address the climate crisis and under the Biden-Harris Administration, America is more energy secure than ever before with the highest domestic energy production on record."

Even if you take the lowest estimate for federal spending under the IRA, 780-800 billion dollars, adding the funds allocated in the CHIPS and BIL laws does exceed the $1 trillion figures that Harris has cited in her campaign speeches. All three laws include provisions that address climate change.

TRUMP CLAIM: Trump suggested he 'probably took a bullet to the head' because of Harris.

FACT-CHECK: False

Trump suggested that the July 13 assassination attempt may have been because of Harris. The FBI has not established a motive that explains why Thomas Matthew Crooks fired on Trump. Trump said, "This is the one that weaponized, not me. She weaponized. I probably took a bullet to the head because of the things that they say about me. They talk about democracy, I'm a threat to democracy. They're the threat to democracy."

During the most recent update on the investigation in a briefing with reporters on Aug. 28, FBI Executive Director Robert Wells said, "At this time, the FBI has not identified a motive nor any co-conspirators or associates of Crooks with advanced knowledge of the attack." "We continue to see through our analysis a mixture of ideologies. So I would say that we see no definitive ideology associated with our subject, either left-leaning or right-leaning. It's really been a mixture and something that we're still attempting to analyze and draw conclusions on," FBI Special Agent in Charge of the Pittsburgh Field Office Kevin Rojek said at the same briefing.

While they do not know what motivated crooks, the FBI does believe he had a mindset to carry out some kind of attack and looked at Trump's Butler rally, about an hour from his home, as a "target of opportunity."

"Regarding the subject's mindset, so we saw, through our analysis of all his - particularly his online searches - a sustained detailed effort to plan an attack on some events, meaning he looked at any number of events or targets. And then when this event was announced, the Trump rally was announced early in July, he became hyper-focused on that specific event and looked at it as a target of opportunity," Rojek said. "Again, I want to stress that we continue to analyze all the evidence associated with his accounts, with his online search activity. And we have a clear idea of mindset, but we are not ready to make any conclusive statements regarding motive at this time."

TRUMP CLAIM: Trump said 'Ashley Babbitt was shot by an out-of-control police officer that should have never, ever shot her. It's a disgrace.'

FACT-CHECK: Misleading

The U.S. Capitol Police Office of Professional Responsibility in August 2021 cleared the officer involved in the shooting of Ashli Babbitt, saying that officer would "not be facing internal discipline."

An internal investigation found the actions of the officer were "lawful and within Department policy," it said.

Babbitt was seen on video on Jan. 6 attempting to kick through a window near the House Speaker's Lobby, shortly after Babbitt entered the Capitol. She was subsequently shot and killed by the officer.

The agency said they'd reviewed all available evidence in connection with the shooting including video and radio calls, and Capitol Police stood by the officer and said his actions saved the lives of lawmakers and family members.

HARRIS CLAIM: Harris said, 'As of today, there is not one member of the United States military who is an active duty in a combat zone, in any war zone around the world, the first time this century.'

FACT-CHECK: False

Harris appears to be using a narrow definition of what constitutes a combat zone, because there are U.S. military troops in the Middle East who have come under deadly fire over the last year.

There are currently 2,500 U.S. military troops in Iraq and more than 900 U.S. military personnel in Syria who are on a mission to support local forces to prevent a resurgence by ISIS. While the troops in both countries are mostly involved in an advisory role some of them are also engaged in risky counterterrorism missions against ISIS. But the real threat to these troops over the past year were the repeated attacks against U.S. bases in both countries by Iranian-backed militia groups that launched more than 170 rocket and drone attacks.

But it was an attack on a U.S. base in neighboring Jordan this past January that has proven to be the most costly. Three U.S. Soldiers were killed and 34 others were wounded when a drone launched by those militia groups made it past air defense systems. That attack led the Biden administration to order large-scale retaliatory airstrikes against the Iranian-backed militia groups.

TRUMP CLAIM: Trump said, 'Iran was broke under Donald Trump. Now Iran has $300 billion because they took off all the sanctions that I had.'

FACT-CHECK: Mostly false, needs context

Trump claimed that if he was in office, Hamas' Oct. 7 attack on Israel never would have happened because the terror group's chief sponsor, Iran, "had no money for terror." However, Iran has been Hamas' principal backer for decades, including through the Trump presidency. Records retrieved from inside Gaza by the Israeli Defense Forces and verified by independent news outlets indicate Tehran funneled tens of millions of dollars during the Trump administration.

Two of Trump's top advisers for Middle Eastern affairs also claimed that Iran was supplying Hamas and other Palestinian terror groups with $100 million each year in an op-ed published in 2019. Trump also said that Iran gained $300 billion because the Biden-Harris administration "took off all the sanctions I had" on Iran.

The current administration has maintained and even levied new sanctions against Iran, but during its attempt to renegotiate an Obama-era nuclear deal that Trump exited in 2018, the U.S. did ease the enforcement of some sanctions and restore a U.N waiver that allowed companies from other countries to conduct non-proliferation work at Iranian nuclear sites.

According to shipping data, Iran's oil exports—its chief source of revenue—have climbed during the last four years. But experts estimate than Tehran has been able to accrue around $100 billion at most during President Biden's term, which is substantially less than Trump's figure of $300 billion.

HARRIS CLAIM: Harris said, 'The former president said climate change is a hoax'

FACT-CHECK: True

Trump certainly has a lengthy record of using the word "hoax" to describe climate change — mostly before and during his first run for president.

On Dec. 30, 2015, Trump told the crowd at a rally in Hilton Head, South Carolina, "Obama's talking about all of this with the global warming and... a lot of it's a hoax. It's a hoax. I mean, it's a money-making industry, okay? It's a hoax, a lot of it." On Jan. 25, 2014, Trump tweeted, "NBC News just called it the great freeze — coldest weather in years. Is our country still spending money on the GLOBAL WARMING HOAX?"

On Jan. 29, 2014, Trump tweeted: "Snowing in Texas and Louisiana, record setting freezing temperatures throughout the country and beyond. Global warming is an expensive hoax!" That same day, he tweeted, "Give me clean, beautiful and healthy air - not the same old climate change (global warming) b-------! I am tired of hearing this nonsense."

Trump also called climate change a "hoax" on the Jan. 6, 2014, edition of Fox & Friends. In addition, he said on the Sept. 24, 2015, edition of CNN's New Day, "I don't believe in climate change." And on Jan. 18, 2016, Trump said that climate change "is done for the benefit of China, because China does not do anything to help climate change."

TRUMP CLAIM: Trump claims Europe giving billions less to Ukraine than the U.S.

FACT-CHECK: False

Trump said the U.S. has committed “250 billion or more” in aid to Ukraine, claiming that European countries meanwhile have paid $150 billion less, despite being more directly affected by the war.

“You take a look at what's happening, we're in for 250 to 275 billion. They're into 100 to 150,” Trump said.

In reality, while the U.S. is easily the largest single donor to Ukraine, European countries collectively have given significantly more and their share recently has increased.

According to Kiel Institute’s Ukraine aid tracker, the U.S. has so far committed nearly $109 billion to Ukraine in military and humanitarian aid, with roughly $25.7 billion still to be allocated.

European countries have committed more than $196 billion -- that is $87 billion more than the U.S., according to the Kiel Institute tracker. However, $85 billion of that also remains to be allocated.

Media reporting often says the U.S. has committed $175 billion to Ukraine through Congressional approvals. But in reality, much of those funds are not destined for Ukraine, but instead goes to the Department of Defense for procurement, operations and maintenance, as well as other programs, according to the Kiel Institute.

The U.S. remains the crucial supporter of Ukraine and is irreplaceable in terms of military equipment and ammunition, which other NATO allies lack in sufficient amounts. When hard-right pro-Trump Republicans in Congress delayed a new aid bill for months, Ukraine began to suffer severe ammunition shortages.
