Harris-Trump debate live updates: High-stakes showdown less than 1 hour away

(PHILADELPHIA) — Vice President Kamala Harris and former President Donald Trump will meet for the first time on Tuesday for the ABC News presidential debate.

It is the only debate the two have scheduled and comes at a critical point as polls show a neck-and-neck race with just eight weeks until Election Day.

The two will face off on key issues starting at 9 p.m. ET. The debate will air on ABC and stream on ABC News Live, Disney+ and Hulu.

Here’s how the news is developing:

1st question on economy

The first question is on an issue that’s top of mind for voters: the economy and cost of living.

Asked if she believed Americans are better off today than they were four years ago, Harris talked about her plans to help families and small businesses. She targeted Trump, saying he will provide a tax cut for “billionaires and big corporations.”

Harris and Trump take the stage

This marks the first time Harris and Trump have ever met.

Harris, Trump shake hands after intro

Harris and Trump shook hands after they were introduced on stage, ending an eight-year streak of no handshakes on the presidential debate stage.

There are no rules or stipulations requiring a handshake before or after the debate.

High-stakes showdown begins

The ABC News presidential debate is now underway.

It is a crucial moment for both candidates with exactly eight weeks until Election Day.

Rep. Madeleine Dean notes the debate will be many viewers’ introduction to Harris

Rep. Madeleine Dean, a Democrat who represents Pennsylvania’s 4th District in the Philadelphia suburbs, said today’s debate is an opportunity for Harris to introduce herself to swing voters outside the political “bubble” who may not have tuned into the campaign earlier, and share her record as a prosecutor, attorney general, senator and now vice president.

“She is an able public servant, and so she has the chance to introduce that part of herself to those who are too busy to actually know all of those granular details,” Dean told reporters in the spin room.

Debate just minutes away

The presidential debate is now just 15 minutes away.

Both candidates have arrived in Philadelphia, and their campaign surrogates are already on the ground providing spin and setting expectations for tonight’s matchup.

Member of exonerated ‘Central Park Five’ in the spin room

New York City Councilman Yusef Salaam, a member of the exonerated “Central Park Five” who was wrongfully incarcerated in connection with a 1989 rape, is in the spin room.

Salaam, who spoke at the DNC, has been a staunch Trump opponent after the former president took out a full-page ad in The New York Times calling for the death penalty for the five suspects at the time.

Rep. Michael Waltz says Trump will pick back up on trade policy

Rep. Michael Waltz, a Florida Republican and veteran who serves on the Armed Services and Foreign Affairs Committees, is one of the Trump surrogates who has been circling the spin room here in Philadelphia. He focused in on Trump’s trade and foreign policy, telling reporters that in a second term, Trump would pick back up on “deals that and “undo executive orders” like the one pausing exports of liquified natural gas.

The debate rules: muted microphones and more

Harris selected the right podium position on stage. The two candidates will remain standing for the 90-minute debate.

There will be no opening statements, though each candidate will get two minutes at the end to give their closing arguments to the American people. Trump will offer the last closing statement after winning the coin toss.

The candidates can’t bring notes on stage. Candidates will only be given a pen, a pad of paper and a bottle of water. They cannot interact with their campaign staff during commercial breaks.

Their microphones will only be live when it is their turn to speak and muted otherwise. Harris and Trump will get two minutes to respond to questions by the moderators and two minutes for rebuttals. They cannot ask each other questions.

Latest look at the debate stage

Here’s the latest look at the debate stage, as Harris and Trump face off in less than an hour.

The candidates will be standing six feet apart. There will be no live audience.

Gavin Newsom tears into Trump, calls him ‘boring’

California Gov. Gavin Newsom, a top Trump antagonist, tore into the former president as unable to resist personal attacks and “boring” on the trail.

“He doesn’t know any other way. He’s incapable of not doing that,” Newsom said when asked if Trump would attack Harris’ personality. “This is a guy who’s just weakness masquerading as strength.”

Newsom said he expects Harris to “rise above” the attacks but to also “counterpunch.”

“She’s new, she’s the next generation. He’s old, he’s stale, he’s derivative, he’s, dare I say it, boring,” Newsom added.

Vivek Ramaswamy says success for Trump is a focus on policy

Vivek Ramaswamy, a former presidential candidate and vocal Trump supporter, said the former president would win a debate centered around policy.

“I think a win looks like a policy-focused debate,” he said.

“If we have a policy-focused debate, Donald Trump hits it out of the park.”

ABC News’ pre-debate special ‘Race for the White House’ begins

“Race for the White House,” ABC News’ prime-time pre-debate special, premiered at 8 p.m. ET.

The special is anchored by chief global affairs correspondent and “This Week” co-anchor Martha Raddatz, chief Washington correspondent and “This Week” co-anchor Jonathan Karl, chief White House correspondent Mary Bruce and senior congressional correspondent Rachel Scott.

You can watch live on ABC, ABC News Live, Disney+ and Hulu.

Pennsylvania a critical battleground this election

Tonight’s debate is being held at the National Constitution Center in Philadelphia.

Pennsylvania has emerged as a central battleground once again after sealing President Biden’s victory over Trump in 2020.

Right now, Harris and Trump are separated by less than 1 percentage point in 538’s polling average of the Keystone State.

Of the seven or so states believed to be in play this cycle, Pennsylvania holds the most electoral votes at 19.

Will the tables turn on Trump’s age and mental fitness?

In the most recent ABC News/Ipsos poll, Harris had an advantage over Trump when it came to who Americans think has better “physical health” and “mental sharpness” to serve effectively as president.

Trump has recently gotten attention for his rambling and often-incoherent speaking style, and while that’s nothing new for him, this will be his first time directly facing a new opponent, who’s nearly 20 years younger than him. Whether or not Trump’s age or mental acuity come up explicitly in tonight’s debate, how he handles himself — and how viewers respond afterward — could help him put some of those concerns to rest, or exacerbate them and give Harris an opening.

Kristi Noem says Trump needs to hold Harris ‘accountable’

South Dakota Gov. Kristi Noem, R, said Trump should hold Harris’ feet to the fire on policy, referencing policies this campaign on things like fracking and health care that differ from stances she took during her 2019 run.

“He needs to hold her accountable to what she truly believes and what she’s done when she was given more power in a bigger position,” Noem told ABC News.

Noem added that accountability should be more focused on policy than personality, but added, “His personality always shines through, it just does, and she’s going to have a tough time dealing with that.”

-ABC News’ Tal Axelrod

Which issues do Americans trust Harris, Trump on?

We’re obviously going to hear about a lot of different issues tonight — and some of those issues will be comfortable ground for Trump, while others will be Harris’ home turf. The latest ABC News/Ipsos poll asked Americans whether they trusted Trump or Harris more to handle 11 different issues. Harris was trusted more on six, Trump was trusted more on four, and one (crime and safety) was tied.

Harris also had the biggest trust advantage on any issue: 16 points, on both abortion and race relations. However, Trump was trusted more than Harris on the three issues that Americans usually say are the most important to their vote: the economy, inflation and immigration.

Melania Trump not in attendance at debate

Members of the Trump family attending the debate with him tonight are his son Eric Trump and his son’s wife — and co-chair of the Republican National Committee — Lara Trump, sources familiar with the matter tell ABC News. Melania Trump is not there.

On the plane with him from Florida to Philadelphia were Florida Rep. Matt Gaetz and former Democratic Rep. Tulsi Gabbard, who have been helping Trump with debate prep. Also on board — one of his lawyers, Alina Habba, as well as senior staffers Chris LaCivita, Susie Wiles, Steven Cheung, Corey Lewandowski and Jason Miller.

Notably, controversial conservative media influencer Laura Loomer was also flying with Trump. Loomer has pushed multiple conspiracy theories about Harris, including racist and sexist attacks on the vice president.

Trump arrives in Philadelphia

Trump landed at Philadelphia International Airport a short while ago for the debate. He could be seen raising his fist as he departed his plane.

Memorable moments from debates past

It’s a hallmark of the American electoral process: the presidential debate.

The first nationally televised debate in history featured John Kennedy and Richard Nixon. The visuals did not play in Nixon’s favor, as he was seen sweating and looking pale after previously being hospitalized for an infection, while Kennedy looked young and gave a more vigorous performance.

More than 20 years later, Ronald Reagan, the oldest sitting president at the time, shut down some questions about his age during his debate with Democrat Walter Mondale.

In 1992’s trilateral debate, President George H.W. Bush was criticized for looking down at his watch. In 2000, Al Gore was mocked for his audible sighs during his debate with George W. Bush.

In the 2020 Democratic primary, one highlight was Harris’ challenge to Joe Biden on the issue of segregation and busing, which prompted her viral quote, “That little girl was me.”

Most recently, the debate between President Biden and Trump changed the course of the 2024 campaign after Biden’s poor performance exacerbated Democratic and voter concerns about his age and fitness to serve another four years. He announced he was exiting the race 24 days later.

Expectations are slightly higher for Harris tonight

Expectations matter in debates. For example, if a candidate goes in with low expectations from the public and turns in a mediocre performance, it probably wouldn’t hurt them as much as if they had gone in with high expectations from the public and turned in the same performance.

Because of this, we were interested in whether Americans had higher expectations of Harris or Trump tonight — so we included this as a question in the most recent ABC News/Ipsos poll. According to that poll, 43% of Americans are expecting Harris to win tonight, while 37% are expecting Trump to win. However, 18% said neither would win or it would be a tie.

Harris, Trump both come into debate with White House track records

Tonight’s debate marks a rare historical moment in that it pits against each other two candidates with significant track records in the White House.

That “political baggage” can be a curse for the candidates, according to experts who’ve studied debates, but also a blessing, depending on how it’s portrayed and defended.

Both Harris and Trump will need to walk a fine line between affirming what they consider their successes during their administrations, experts said.

-ABC News’ Ivan Pereira

Trump is viewed more negatively than Harris

Debates are a rare opportunity for candidates to change their perception among the American people. And right now, Harris is perceived more positively than Trump. According to 538’s polling average, 46 percent of Americans view her favorably, while 47 percent view her unfavorably. While that’s not exactly popular, it’s a remarkable reversal from just a couple months ago. Before Biden dropped out of the presidential race, Harris had a net favorability rating of -16 points. But since she kicked off her campaign, her favorable rating has shot up, while her unfavorable rating has plummeted.

By contrast, according to 538’s polling average, 43% of Americans view Trump favorably, while 53% view him unfavorably. Those numbers have been pretty consistent over the years. Trump’s unfavorable rating has been about 10-15 points higher than his favorable rating since he left office in 2021, and his average job approval rating was in the same range for most of his term as president.

Rick Scott says Trump will be focused

As speculation mounts over how Trump will go after Harris — on policy or personality — Sen. Rick Scott, R-Fla., a top Senate ally, insisted the former president will stick to issues Americans care about.

“He’s going to do great,” Scott told reporters in the spin room in Philadelphia. “He’s going to talk about the issues.”

-ABC News’ Tal Axelrod

Entering the debate, the race is basically tied

The stakes for this debate are high for both candidates for one very simple reason: The presidential race is extremely close right now. In some of the states most likely to decide the election — such as Pennsylvania, Georgia and North Carolina — 538’s polling averages show Harris and Trump within 1 percentage point of each other.

Nationally, Harris leads Trump by an average of almost 3 points, raising the possibility that she could win the popular vote but lose the Electoral College, as Hillary Clinton did in 2016. According to 538’s average, Harris’s national lead peaked at 3.7 points on Aug. 23, the day after the Democratic National Convention, but her advantage has slipped a bit in the weeks since.

Harris and Trump face major challenges, risks on debate stage

Harris and Trump will need to navigate the pitfall-filled debate of their political lives as each tries to persuade millions of voters and viewers that they’re the one best suited to be president.

Harris, whose wave of momentum has brought Democrats back to a neck-and-neck presidential race, will have to prosecute the case against Trump while also laying out how her agenda could help the country — particularly beleaguered middle- and working-class Americans.

Trump, meanwhile, has the task of casting his record on the economy and immigration as superior to Harris’ while avoiding distracting personal attacks on Harris.

Republicans and Democrats told ABC News how they should meet the crucial moment.

Tonight’s presidential debate presents rare opportunity to shape election: Experts

How much difference do presidential debates make? In the past, they’ve rarely influenced an election’s outcome, according to historians who spoke with ABC News.

But the June debate between President Joe Biden and former President Trump was a rare exception, they say, ultimately leading to an unprecedented change in the Democratic presidential ticket.

Now as Vice President Harris prepares to take on Trump in their first presidential debate, experts predict the matchup could potentially produce a similar consequential and history-making moment that could sway undecided voters — a key voting bloc that could determine who wins the November election.

Independent voters want to know more about Harris. Can she fill in the gaps?

A recent New York Times/Siena College poll found a sizable share of likely voters (28%) and registered voters (31%) feel they need to know more about Harris as a candidate. Those numbers were even higher among independent voters: 41% of registered independents and 38% of likely voters who identified as independent said they needed to learn more about her.

Her campaign is well-aware that a large slice of the critical voting bloc feels they don’t know Harris well enough, ABC News Chief White House Correspondent Mary Bruce reports.

Tonight, she’ll want to fill in the blanks in what is her highest-profile appearance since her acceptance speech at the Democratic National Convention last month. But beyond that, their real goal is to make clear the stark choice in this election between what she wants to do as president and what Trump intends to do.

Newsom, Shapiro, Duckworth among Harris spin room surrogates

The Harris campaign released its list of surrogates who will be in the spin room during the debate.

Four Democratic governors — Roy Cooper of North Carolina, Michelle Lujan Grisham of New Mexico, Gavin Newsom of California and Josh Shapiro of Pennsylvania — are among the group, as well as Sens. Laphonza Butler of California, Tammy Duckworth from Illinois and Chris Murphy of Connecticut.

Four Democratic House members — Jason Crow from Colorado, Veronica Escobar of Texas, Robert Garcia from California and Ted Lieu of California — will also be joining, as well as retired Brig. Gen. Steve Anderson, a former Republican; Reproductive Freedom for All President and CEO Mini Timmaraju and Khizr Khan, a Gold Star father.

Biden says he spoke with Harris, who appears ‘calm, cool and collected’

As he left the White House for New York, where he will watch tonight’s debate, President Joe Biden said he’s spoken with Harris.

Biden wouldn’t divulge what advice he had for her, but said she appeared “calm, cool and collected.”

“I think she’s going to do great,” Biden said.

Hillary Clinton said Kamala Harris should ‘bait’ Trump during tonight’s debate

Hillary Clinton gave some advice to Vice President Kamala Harris on tonight’s debate, according to The New York Times.

“She just should not be baited. She should bait him. He can be rattled,” Clinton told The Times during a recent phone interview.

Clinton confirmed to NYT that she had spoken to Harris directly and discussed “a number of things” prior to the debate.

As the 2016 Democratic nominee, Clinton has experience debating the former president.

She said she believes Harris “has a lot of good ammunition” and that she’s “handling him [Trump] very well.”

RNC Chairman Michael Whatley says Trump’s ‘rested,’ ‘relaxed’ and ‘ready to go’

In an interview Tuesday with ABC News’ Kyra Phillips, Republican National Committee Chairman Michael Whatley said it was unfair of the Harris campaign to suggest Trump would lie on stage tonight.

He also confirmed that Trump will stray away from personal attacks, and that the former president was not nervous.

“He feels very comfortable. He’s rested, he’s relaxed, and he’s definitely ready to go,” Whatley said.

Whatley also said “this is the most united the Republican Party has been in generations.”

Presidential candidates haven’t shaken hands at debate since 2016

There are no rules requiring Harris and Trump to shake hands before or after the debate.

If they do, it would mark the first time since 2016 that the candidates have shaken hands. Trump and Biden did not shake hands during their two matchups in 2020.

Trump contracted COVID-19 following the first debate.

The two candidates also didn’t shake their hands during the June debate.

Trump campaign says he’s in ‘good spirits’

The Trump campaign during a pre-debate call said Trump is in “good spirits” and will be departing shortly for Philadelphia.

“President Trump is in good spirits. He is currently in Mar-a-Lago. My understanding is that he will be departing shortly to head over to Philadelphia,” said Trump campaign senior adviser Danielle Alvarez when asked about his mood going into the debate.

She suggested that the former president is “ready” to talk about inflation, housing affordability and the border among other issues on the debate stage. Alvarez also suggested that Trump might attack Harris for flip-flopping on some key issues such as fracking, police funding and electric vehicles.

“The president is certainly full of surprises. I know that we can expect him to be, you know, with his, his charming self. We know that he is incredible when it comes to weaving in and out of topics — he’s incredible on those policy issues. So that’s … certainly something that may happen,” she said.

First to ABC: Sens. Chris Murphy, Laphonza Butler in spin room for Harris

Sens. Chris Murphy and Laphonza Butler will be in the spin room as surrogates supporting Harris, according to a campaign official. This news is being shared first with ABC News.

Murphy had helped negotiate the bipartisan border deal earlier this year that Trump urged his party to oppose. Harris has been pledging to work to get that deal passed if elected, while hammering Trump for killing the deal.

Butler met Harris 15 years ago when Harris was the district attorney of San Francisco and Butler also served as senior adviser on Harris’ 2020 presidential campaign.

Harris, Trump campaigns spin expectations ahead of ABC News debate

Harris said in an interview that aired Monday that she expects former President Donald Trump to lie during the ABC News presidential debate on Tuesday.

Meanwhile, the Trump campaign and surrogates continued to insinuate on Monday that the former president’s strategy at the debate will be to tie Harris to what they say are her policy failures and “disasters” as a leader of the Biden-Harris administration.

With time ticking down until the two meet for the debate, both candidates are working to spin expectations in what is expected to be a key moment for both campaigns as they look to appeal to voters ahead of what’s expected to be a close contest in November.

Khan garnered national attention after he delivered a blistering speech attacking Trump at the 2016 Democratic National Convention.

Harris will also be supported in the spin room by retired Brig. Gen. Steven M. Anderson, according to the campaign official. NBC News first reported Khan and Anderson’s roles as Harris surrogates in the spin room.

Trump campaign spokesperson says he’s not engaged in traditional debate prep

Trump campaign spokesperson Danielle Alvarez said Tuesday morning on ABC News Live that Trump “does not do traditional debate prep” and reiterated that he has been campaigning and engaging in policy discussions instead.

“I would say that the president does not do traditional debate prep. He’s on the campaign trail constantly. We see him in key battleground states every week, joined by tens of thousands of patriots,” she said. “We know that he does tough interviews, both nationally, locally.”

“That’s truly how he prepares for these debates, having those conversations every day. He’s ready to step back into the White House,” she continued. “We also know that he prefers to have those policy discussions, and he’s been doing that with elected members in Congress like Matt Gaetz, with former Congress member Tulsi Gabbard and others — very similar to what he did to prepare for that first debate against Joe Biden. He has prepared in a similar way again, just by getting out there and talking every day to voters and talking to media.”

Harris not ‘underestimating’ Trump ahead of debate: Source

Just hours away from the debate, a campaign source is setting expectations that Harris is not “underestimating” Trump’s ability to debate, and that it would be a “mistake” to do so.

The Harris team expects Trump to be “good” at debating, stressing that Trump has done this more than anybody else, while it will be Harris’s first presidential debate.

The Harris campaign is “happy to get under [Trump’s] skin,” and they hope that bringing former Trump officials into the spin room later this evening will accomplish this.

On a campaign call last night, a source said Harris is ready for any version of Trump that shows up — whether it’s the presidential Trump, the more mellow Trump during the Biden debate or a more aggressive version.

Harris and Trump square off Tuesday at what could be their only presidential debate, setting high stakes for an event expected to be viewed by millions of Americans and a key sliver of undecided voters. Here’s what to look out for.

Can Trump stay focused on policy? Staying on message on his four-year economic record is key, while veering into personal attacks would be counterproductive, allies told ABC News.

Harris has dual goals: make the case for herself as someone who would be a capable president and get under Trump’s skin. How will she introduce herself to undecided voters?

Harris releases new ad repurposing Obama’s dig at Trump

Vice President Kamala Harris repurposed former President Barack Obama’s suggestive dig at Trump over what Obama called his “weird obsession with crowd sizes” while speaking at the Democratic National Convention last month.

“Here’s a 78-year-old billionaire who has not stopped whining about his problems …” Obama said in the clip used in the ad, just before a clip of Trump at rally plays.

“Ooh, she had a big crowd! Ooh, that crowd,” Trump said in the snippet, mocking news reports about turnout for Harris.

“This weird obsession with crowd sizes… it just goes on, and on, and on,” Obama says as the ad returns to him, followed by shots of small Trump crowds and sounds of crickets chirping.

“America’s ready for a new chapter. We are ready for a President Kamala Harris,” Obama says.

The Harris campaign said the ad, titled “Crowd Size,” will air on Fox News the day of the debate because “Trump is known to watch” the network.

The 30-second ad is set to air nationally on cable news and in local West Palm Beach and Philadelphia markets.

Scaramucci served as Trump’s White House communications director. Troye served as the Homeland Security adviser to Vice President Mike Pence, as well as a top aide on the Trump White House coronavirus task force.

According to the campaign, they plan to discuss their support of Harris ahead of tonight’s debate.

They are among numerous former Trump staffers who continue to speak out.
