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.

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 6 feet apart. There will be no live audience.
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, 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."
