How to Watch the ABC News Presidential Debate Live: Kamala Harris and Donald Trump Face Off in Philly

Vice President Kamala Harris and former President Donald Trump are finally set to meet for their first debate of the 2024 presidential election season on Tuesday, Sept. 10.

The matchup between Harris, 59, and Trump, 78, may be the only one before Election Day on Nov. 5, as no additional debates are currently scheduled between the nominees. Their campaigns have suggested that they are open to putting another on the calendar.

The showdown — which will mark Harris and Trump's first time standing face to face — follows a chaotic couple of months for both candidates.

Trump was wounded in an assassination attempt at a Pennsylvania campaign rally on July 13, days before he accepted his party's nomination at the Republican National Convention.

Harris, on the other hand, only entered the race on July 21, after President Joe Biden made the shocking move to end his reelection campaign as a direct result of his June debate performance against Trump. Within weeks of taking Biden's place at the top of the ticket, Harris formally accepted the Democratic Party's nomination.

Trump was long considered the frontrunner of the 2024 election, as Biden, 81, struggled to overcome low favorability ratings and concerns about his age. Since Harris stepped in, Democrats have seemingly leveled the playing field, making the candidates' matchup on Tuesday a high-stakes occasion.

Read on for everything to know about the first presidential debate between Harris and Trump on Sept. 10.

How to Watch Live and Where to Stream

Host network ABC News will make the debate widely available on all its platforms. The presidential debate — which runs from 9-10:30 p.m. ET on Tuesday, Sept. 10 — will air live on ABC and will stream live on ABC News Live, Disney+ and Hulu.

The full debate will also be made available to podcast listeners on ABC News' podcast Start Here.

In an effort to make Harris and Trump's first presidential debate as accessible as possible, ABC News has also given other news networks permission to air the event, meaning you can stream the debate on most platforms where you get live news.

Some outlets will stream the debate for free online for those without cable or streaming apps. PBS News, for example, is expected to air the debate for free on its YouTube channel.

Who Is Moderating the Debate?

ABC News' David Muir and Linsey Davis were tapped to host ABC News' presidential debate on Tuesday.

Muir, 51, is anchor and managing editor of ABC World News Tonight and has moderated multiple presidential primary debates. He has previously interviewed both Trump and Harris.

Davis, 46, anchors the Sunday edition of World News Tonight as well as Prime which airs on ABC News Live, the network's 24/7 streaming news channel. She has also moderated presidential primary debates.

George Stephanopoulos, a former White House communications director for Bill Clinton who now leads much of ABC News' political coverage, will notably be absent at the debate. Stephanopoulos, 63, is the subject of a lawsuit filed by Trump earlier this year, which claims that the ABC News anchor defamed him by saying on the air that Trump was found liable of "raping" former Elle columnist E. Jean Carroll (the former president was found liable of sexual abuse, not rape).

Trump has repeatedly expressed his disdain for Stephanopoulos on the campaign trail, likely contributing to ABC News' choice of debate moderators.

What Are the Harris-Trump Debate Rules?

Trump and Harris battled over the rules of the debate in recent weeks. Trump's campaign reportedly wanted to keep microphones muted when candidates aren't speaking and restrict candidates from bringing notes on stage with them. Harris' campaign wanted microphones to stay unmuted, seemingly so that viewers at home could hear when Trump was being disruptive and so that Harris would have more chances to shut him down.

Trump ultimately got his way, with ABC News announcing that candidates had agreed on the same debate rules that Trump and Biden followed during CNN's debate in June, which means microphones will be muted when candidates are not speaking, and no props or pre-written notes will be allowed on stage. Each candidate will be provided a pen, pad of paper and water bottle.

During the program, candidates will have two minutes to answer each question and two minutes for rebuttals. They can get an extra minute if they have a follow-up question, clarification or response.

On stage, candidates must remain behind their podiums. During commercial breaks, they may not consult with their campaign staff.

When Is the Vice Presidential Debate?

Minnesota Gov. Tim Walz, the Democratic vice presidential nominee, is currently scheduled to debate Ohio Sen. J.D. Vance, the Republican vice presidential nominee, one time before the election.

Walz, 60, and Vance, 40, will take the stage in New York City on Oct. 1 to defend their respective parties' platforms. The vice presidential debate, coordinated by CBS News, will be moderated by CBS Evening News anchor Norah O'Donnell and Face the Nation moderator Margaret Brennan.
