Harris and Trump sparred in the high-stakes showdown.
The first presidential debate between Vice President Kamala Harris and former President Donald Trump turned into a heated matchup that lasted more than 90 minutes.
The night started with a handshake initiated by Harris, but quickly escalated as the vice president bashed Trump over his policies and comments, contending that it was time to "offer is a new generation of leadership for our country."
Trump criticized Harris throughout the debate on topics such as Afghanistan and immigration issues, drawing comparisons between the vice president and President Joe Biden.
With Election Day just eight weeks away, the debate came at a critical point as polls show a neck-and-neck race between the candidates.
Harris and Trump met for their first presidential debate on Tuesday night. The consequential matchup was hosted by ABC News at the National Constitution Center in Philadelphia.

The Harris campaign will fly a drone show over the Philadelphia Art Museum from 8:05 to 8:25 p.m. ET at the famous Rocky Steps, just prior to the debate on Tuesday.
The show will add onto the campaign’s Philly-themed advertising and recent ad mocking Trump and crowd sizes, according to campaign spokesperson Kevin Munoz.

At a campaign fundraiser Tuesday morning, Gov. Tim Walz said he knew what to expect from Trump during the debate, calling the former president a "showman," according to a pool reporter in the room.
"Donald Trump's a showman. This is his seventh general election debate. No one in modern times has done more of these. The good news is that this is his seventh debate and we know exactly what to expect," Walz said.

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.
