The second presidential debate was held on Tuesday, September 10, 2024, at 9:00 p.m. EDT at the
National Constitution Center in
Philadelphia,
Pennsylvania.
Prelude The Biden and Trump campaigns had agreed to a September 10 debate hosted by
ABC, but after Biden suspended his re-election campaign, it became unclear whether Trump would debate a new rival candidate. In late July, after Harris secured enough support to become the presumptive nominee, Trump said he would debate her repeatedly, though he said he preferred not to do so on ABC.
Fox News extended invitations to Harris and Trump for a proposed debate to place on September 17 in Pennsylvania. Harris indicated on July 25 she was willing to debate Trump on ABC. Trump's communications director,
Steven Cheung, remarked the same day that the Trump campaign would not commit to any debate until the Democratic Party formally nominated its candidate. On August 2, Trump stated that the planned September 10 debate would be "terminated" since Biden would no longer be a participant and instead he had "agreed with Fox News" to a September 4 debate with a live audience, which Harris never accepted. In an August 8 press conference, Trump announced he would rejoin the September 10 debate, though he made it contingent on Harris agreeing to two other proposed debates, stating that if Harris only agrees to the ABC debate, "I don't know how that's gonna work out. We'd like to do three debates." Harris and Trump verbally sparred over attending the debates. On August 15, the Harris campaign said a second debate would be contingent on Trump "actually showing up" to the September 10 debate. On August 27, Trump recommitted to the September 10 debate.
Qualifications In order to qualify for the September 10 ABC debate, presidential candidates needed to meet the following criteria: • Be
constitutionally eligible to hold the presidency • File with the
Federal Election Commission • Appear on a sufficient number of ballots to have a mathematical possibility of winning a majority vote in the
Electoral College • Agree to the rules of the debate • Have a level of support of at least 15% in four national public polls of registered or likely voters selected by ABC, with such polls dating between August 1 and September 3, 2024. Harris and Trump were invited to the debate in early August. Five polls met ABC's criteria for inclusion, with Harris and Trump meeting the 15% threshold in every poll. Kennedy peaked at 6% in a Fox News poll. West, Stein, and Oliver all peaked at 1% support, and no other candidate was tested.
Preparations Harris prepared for the debate in
Pittsburgh.
Karen Dunn and Rohini Kosoglu were in charge of the preparations and
Philippe Reines played Trump. Trump prepared for the debate with a small team of advisers, including
Matt Gaetz and
Tulsi Gabbard.
Format The debate was hosted on
ABC,
ABC News Live,
Disney+ and
Hulu, and was
simulcast on CNN, Fox News, MSNBC, NBC News and other networks. The debate rules remained the same as the one prior, with no audience being present and muted microphones.
Debate At the start of the debate, Trump moved behind his lectern, but Harris approached him and extended her hand. It was the first presidential debate to begin with a handshake
in eight years. In the hours leading up to the debate, social media was flooded with reports of baseless allegations—echoed by JD Vance, Trump's running mate, and Trump himself—that
Haitian migrants in
Springfield,
Ohio,
were stealing and eating cats and dogs. Despite city officials stating there were no credible reports to substantiate these claims, Trump raised the issue during the debate. He said: "In Springfield, they're eating the dogs. The people that came in, they're eating the cats. They're eating—they're eating the pets of the people that live there." He cited nothing but claimed he heard it on television. Harris laughed as Trump made those statements. Harris accused Trump of repeatedly exploiting the issue of race to "divide the American people". The remark came after a question from the moderators about a July remark in which he said Harris "became a Black person". Trump argued that the Biden administration had "destroyed" the country, and falsely labelled Harris a
Marxist and tried to portray Harris as a "radical liberal". He claimed: "She has a plan to defund the police. She has a plan to confiscate everyone's guns." Harris responded, stating: "Tim Walz and I are both gun owners. We're not taking anybody's guns away." Trump remarked, "Remember this, she is Biden." Harris responded: "Clearly, I am not Joe Biden." Trump attacked Harris on inflation during his statement on the economy and said "Look, we've had a terrible economy because inflation has -- which is really known as a country buster. It breaks up countries. We have inflation like very few people have ever seen before. Probably the worst in our nation's history. We were at 21%. But that's being generous because many things are 50, 60, 70, and 80% higher than they were just a few years ago." Trump also attacked Harris on
immigration saying "we have millions of people pouring into our country from prisons and jails, from mental institutions and insane asylums. And they're coming in and they're taking jobs that are occupied right now by African Americans and Hispanics and also unions." Harris invited people to attend a Trump rally and observe the crowd. "People start leaving his rallies early out of exhaustion and boredom," she said. Trump responded by saying: "People don't go to her rallies. There's no reason to go. And the people that do go, she's busing them in and paying them to be there." Some of Harris's sharpest criticisms of Trump occurred during their clash over
abortion rights, a key issue for Democrats since the US Supreme Court overturned
Roe v. Wade in 2022 with ''
Dobbs v. Jackson Women's Health Organization''. Harris said: "One does not have to abandon their faith or deeply held beliefs to agree the government—and Donald Trump, certainly—should not be telling a woman what to do with her body." She said she would restore women's rights to what they were under
Roe, and Trump responded that she would not have the votes necessary in Congress. Trump supported the
Dobbs decision to have each state decide whether to ban abortion, but did not answer whether he would veto a hypothetical bill to ban abortion nationwide. Trump claimed that Harris supported "
defunding the police", prompting Harris to interject with "That's not true" into her muted mic. In response to this perceived interruption, Trump lashed out at Harris with the line "I'm talking now (...) Does that sound familiar?", a reference to Harris's notable "I'm speaking" line from the
2020 vice presidential debate with
Mike Pence. Trump heavily criticized the
Affordable Care Act, though he claimed to have "saved" it. When asked if he had a plan of how to replace the act, Trump claimed he had "concepts of a plan". "Concepts of a plan" ended up being one of the more frequently-quoted lines in the debate's aftermath. When moderators questioned him about any regrets regarding the
January 6 Capitol attack, he denied responsibility and redirected the conversation to
Black Lives Matter protests. He blamed then-Speaker of the House
Nancy Pelosi for not accepting his alleged offer of sending the
National Guard, which the Speaker does not control. He initially used "we" when referring to the January 6 protestors and then pivoted, saying: "This group of people that has been treated so bad." Trump was repeatedly asked if he wanted
Ukraine to win its
war against Russia and if it was in the best interests of the U.S. for Kyiv to achieve victory. He did not address the question directly, stating instead that he wants the war to end in order to save lives. Harris told Trump, "[Putin] would eat you for lunch" and claimed that if he had been president when Russia invaded Ukraine, "Putin would be sitting in Kyiv right now." She alleged that Trump's claim that the war would be over in 24 hours was based on the idea that he would simply concede to Putin.
Fact-checking The moderators were tasked with fact-checking the candidates during the debate, and multiple news outlets did so as well. CNN found that Trump made over 30 false claims during the debate, and Harris only made one, along with several statements "that were misleading or lacking in key context." When Trump repeated the debunked allegation that immigrants in Springfield were eating pets, the moderator David Muir responded that there had been no credible reports of pets being harmed. Trump countered by claiming he had seen TV interviews where people said their dogs had been taken and eaten. Trump claimed that there was virtually no inflation during his presidency. However, the
consumer price index rose 7.1% during his first 45 months in office. Trump claimed that some babies were being subjected to "executions" after birth. Davis intervened to fact-check him, stating: "There is no state in this country where it is legal to
kill a baby after it's born." Trump also said that "A lot of these illegal immigrants coming in, [Democrats] are trying to get them to vote"; however, it is illegal for noncitizens to vote in federal elections. Harris also made misleading and false claims during the debate, including that Trump "exchanged love letters" with
North Korean dictator
Kim Jong Un. Trump had only said the two leaders had fallen "in love". Harris also denied Trump's claim, that she is in support of spending taxpayers' money on gender affirmation surgeries on prison inmates, as one of his "lies." However, a video from her unsuccessful
2020 Democratic Party presidential primaries surfaced of her pledging to provide gender affirming care to detained migrants.
Viewership Nielsen Media Research reported that 67.1 million viewers across ABC and 16 other television networks watched the debate, up from the 51.3 million viewers who watched the June 27 presidential debate between Biden and Trump; an additional seven million viewed through Disney-owned streaming platforms.
Reception and aftermath video covering early reactions to the debate Harris was declared the winner of the debate by columnists from
CNN,
Politico,
The New York Times,
USA Today,
Business Insider,
Vox, The Guardian,
MSNBC, and the
Los Angeles Times. According to a CNN flash poll, 63% of text message respondents believed Harris won the debate, while 37% felt Trump won. A poll from
YouGov showed 43% of respondents saying that Harris won, 28% saying that Trump won, and 30% unsure. A poll from
Reuters and
Ipsos showed 53% of respondents saying that Harris won, as opposed to 24% saying that Trump won. According to
Amy Walter, editor of the nonpartisan
The Cook Political Report, Harris won the debate by successfully turning it into a referendum on Trump, while Trump did not make a consistent or compelling case against Harris. Muir and Davis's fact-checking approach to the debate received criticism from Republicans, who alleged they fact-checked and interrupted Trump excessively while not doing the same to Harris. Trump echoed those complaints and suggested
ABC News should lose its license. Other journalists and Republican pollster
Frank Luntz praised their moderation. Trump's campaign strategists had urged him to emphasize in the debates that he was a "changed man" who had survived an
assassination attempt and would unite America, but they believed he had been unable to do so.
Facebook satire page "America - Love It Or Leave It" posted a claim that Harris was found to have made up to 17 false claims within the first ten minutes of the debate. This was widely circulated around social media after the debate. Many of Trump's statements during the debate, such as "They're eating the dogs ... they're eating the cats ... they're eating the pets", "execution after birth", "
transgender operations on illegal aliens in prison", "
Abdul ... the
head of the Taliban", and "I have concepts of a plan" became viral
Internet memes in its aftermath, as did Harris's facial expressions in response to Trump's statements. At one point, while criticizing Trump over inviting the
Taliban to
Camp David and the deal that would eventually lead to the
Afghan withdrawal, Harris referred to Trump as "this former president", pausing between "this" and "former president". In media coverage of the debate, some commentators drew attention to the pause, suggesting that Harris was avoiding using an insult or an expletive. After the debate, polls showed Harris still had a hard time conveying the perception that she would represent a "change" in policy, due to her being a part of the
Biden administration. ABC News won a special citation for the Harris-Trump debate at the 2026
