The ground rules for this presidential debate
Biden and Trump will stand at lecterns decided earlier by a coin flip. Their microphones will be muted unless it is a candidate's turn to speak, CNN said, which is likely to limit how much the candidates can interrupt each other.
Though it's yet not clear who will control the ability to mute the candidates' microphones, the moderators "will use all tools at their disposal to enforce timing and ensure a civilized discussion," according to the network.

According to CNN's rules, Biden and Trump won't be allowed to use any props or pre-written notes, but will be given paper, a pen and water. Their campaign staffs will not be allowed to interact with them during the debate.
There will be no opening statements. The coin flip determined Biden would stand at the podium to the viewer's right, while Trump would deliver the final closing statement.
Going without a live audience was important to the Biden campaign, but also to CNN. The network's town hall with Trump in 2023 was panned in large part because of the presence of Trump partisans.
