Vice President Kamala Harris and former President Donald Trump are set to face off in person for the first time in a debate on Tuesday at Philadelphia’s National Constitution Center.

With President Joe Biden out of the race, Harris closed the polling gap, making the contest neck-and-neck two months before the election. 

The 90-minute debate will air live on ABC News at 9 p.m. ET, with muted microphones and no live audience.

Harris’s campaign has criticized the format, saying it shields Trump from direct exchanges. 

According to the rules, no candidate will have advance access to questions. Each person will have two minutes to respond and one minute for follow-ups. Closing statements are limited to two minutes.

Trump won the coin flip, choosing to give the final closing statement, while Harris secured the right podium position.
