ABC has announced the complete set of rules for its Sept. 10 presidential debate between Vice President Kamala Harris and former President Donald Trump.

The debate will air at 9 p.m. Eastern Time on ABC and its platforms, including Disney+ and Hulu. ABC anchors David Muir and Linsey Davis will moderate.

The debate will run for 90 minutes. The candidates selected certain aspects of the debate based on a coin flip: Trump chose to give his closing statement last, and Harris chose to stand at the rightmost podium on screen during the broadcast.

Each candidate will get two minutes to answer questions, two minutes to deliver rebuttals, and one minute for responses or follow-ups as granted.

Closing statements will run for two minutes per candidate and there will be no opening statements.

Microphones will be muted for candidates except when they have been granted speaking time.

Candidates have not received information about debate questions beforehand. Candidates are not permitted pre-written notes, though each will have a pad and pen available during the debate.
