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.

President Joe Biden will be watching the debate from New York, where he's going to be for 9/11 memorial events, according to White House press secretary Karine Jean-Pierre.
"The president will definitely be watching," she said in Monday’s briefing.

"She's going to show everyone watching what this movement is all about: supporting families like yours and mine and building a future where everyone has the opportunity not just to get by, but to get ahead," the email reads. "Donald Trump is sure to talk about his twisted version of freedom," Walz claimed in the email.
