Harris and Trump are sparring 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.
The presidential debate is now just 15 minutes away.
Both candidates have arrived in Philadelphia, and their campaign surrogates are already on the ground providing spin and setting expectations for tonight's matchup.
New York City Councilman Yusef Salaam, a member of the exonerated "Central Park Five" who was wrongfully incarcerated in connection with a 1989 rape, is in the spin room.
Salaam, who spoke at the DNC, has been a staunch Trump opponent after the former president took out a full-page ad in several New York newspapers calling for the death penalty for the five suspects at the time.
Rep. Michael Waltz, a Florida Republican and veteran who serves on the Armed Services and Foreign Affairs Committees, is one of the Trump surrogates who has been circling the spin room here in Philadelphia. He focused in on Trump's trade and foreign policy, telling reporters that in a second term, Trump would pick back up on "deals [that] were moving and then were undone" to address the trade deficit with China and "undo executive orders" like the one pausing exports of liquified natural gas.
