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 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.
