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.

Tonight's presidential debate presents rare opportunity to shape election: Experts

How much difference do presidential debates make? In the past, they've rarely influenced an election's outcome, according to historians who spoke with ABC News.

Independent voters want to know more about Harris. Can she fill in the gaps?

A recent New York Times/Siena College poll found a sizable share of likely voters (28%) and registered voters (31%) feel they need to know more about Harris as a candidate. Those numbers were even higher among independent voters: 41% of registered independents and 38% of likely voters who identified as independent said they needed to learn more about her.

Her campaign is well-aware that a large slice of the critical voting bloc feels they don't know Harris well enough, ABC News Chief White House Correspondent Mary Bruce reports.

Tonight, she'll want to fill in the blanks in what is her highest-profile appearance since her acceptance speech at the Democratic National Convention last month. But beyond that, their real goal is to make clear the stark choice in this election between what she wants to do as president and what Trump intends to do.
