The June presidential debate hosted by CNN between President Joe Biden and Trump saw several changes from traditional debate rules, including a lack of audience and muted microphones. While the Trump and Harris campaigns attempted to negotiate new terms for the ABC News debate, the guidelines have remained largely the same from the first one. Here are the rules both candidates will have to follow during the Tuesday debate in Philadelphia.

Muted microphones

Biden’s campaign had pushed for muted microphones in the CNN debate in June, a rule change that appeared to actually help Trump in their faceoff. Ahead of the ABC News debate, the Harris campaign attempted to reverse the rule to have microphones live throughout the debate, but the Trump campaign said the rules would not be renegotiated, even as Trump said he did not mind having microphones live throughout.

ABC News confirmed last week that microphones “will be live only for the candidate whose turn it is to speak and muted when the time belongs to another candidate.”

Questions and responses

ABC News’s David Muir and Linsey Davis will ask the candidates questions during the debate. The rules state that candidates are not permitted to ask questions of each other.

ABC News has said that there will be no opening statements but that each candidate will get a two-minute closing statement. Harris will get the first closing statement, while Trump will get the final word with his after he won a coin flip to select either the placement of the podium or closing statement order.

Each candidate will have two minutes to answer questions, two minutes for rebuttals, and “one extra minute for follow-ups, clarifications, or responses,” according to ABC News. The outlet has also said that no topic or questions will be given to either of the campaigns ahead of the debate.

Venue

The debate between Harris and Trump will be held at the National Constitution Center in Philadelphia, with no audience present in the debate hall.

Harris will be at the podium on the right side of the screen, while Trump will be on the podium on the left side of the screen. Both candidates will enter the debate stage from opposite sides of the stage and will be introduced by Muir and Davis. Harris will enter first, as the Democrats are the incumbent party in the White House.

Both candidates will stand behind their podiums throughout the debate, while Muir and Davis will be seated. At the podium, both candidates will have a pen, a pad of paper, and a water bottle, but neither will be allowed to bring prewritten notes or props to their podium.

Other rules

The debate will be 90 minutes long with two commercial breaks, as was seen with the CNN debate in June. During the two commercial breaks, campaign staff will not be allowed to interact with their candidate.

ABC News has also said the moderators “will seek to enforce timing agreements and ensure a civilized discussion.”

The debate will air on ABC, along with on ABC News Live, Disney+, and Hulu. Live simulcasts of the debate will also be available on CBS, Fox, NBC, and PBS, along with on various cable networks including C-SPAN, CNN, Fox News, MSNBC, and NewsNation.

The debate is scheduled to begin at 9 p.m. Eastern on Tuesday. Another presidential debate between Harris and Trump has yet to be agreed to, but vice presidential candidates Gov. Tim Walz (D-MN) and Sen. J.D. Vance (R-OH) have agreed to a debate hosted by CBS News on Oct. 1.
