LIVE BLOG: Donald Trump vs Kamala Harris Presidential Debate

With only weeks until Election Day, the debate is a crucial opportunity for both candidates to work to sway undecided voters in what's expected to be a close contest.

The debate is a chance for Harris -- who became the Democratic candidate after President Joe Biden left the race following his lackluster June debate performance -- and Trump to explain their policies on key issues. It's the first time the pair will meet in person.

Here's what to know about the debate and how to tune in.

What are the ground rules?

Both Harris and Trump accepted the debate rules, which include that their microphones will be muted when the time belongs to another candidate.

The agreed-upon rules include:

  • The debate will be 90 minutes with two commercial breaks.
  • The two seated moderators will be the only people asking questions.
  • A coin flip was held virtually on Tuesday, Sept. 3, to determine podium placement and order of closing statements; former President Donald Trump won the coin toss and chose to select the order of statements. The former president will offer the last closing statement, and Vice President Harris selected the right podium position on screen (stage left).
  • Candidates will be introduced by the moderators.
  • The candidates enter upon introduction from opposite sides of the stage; the incumbent party will be introduced first.
  • No opening statements; closing statements will be two minutes per candidate.
  • Candidates will stand behind podiums for the duration of the debate.
  • Props or prewritten notes are not allowed onstage.
  • No topics or questions will be shared in advance with campaigns or candidates.
  • Candidates will be given a pen, a pad of paper and a bottle of water.
  • Candidates will have two-minute answers to questions, two-minute rebuttals, and one extra minute for follow-ups, clarifications, or responses.
  • Candidates' microphones will be live only for the candidate whose turn it is to speak and muted when the time belongs to another candidate.
  • Candidates will not be permitted to ask questions of each other.
  • Campaign staff may not interact with candidates during commercial breaks.
  • Moderators will seek to enforce timing agreements and ensure a civilized discussion.
  • There will be no audience in the room.
