Next month’s debate between Vice President Kamala Harris and former President Donald Trump won’t have an audience, live microphones when candidates aren’t speaking, or written notes, according to rules that ABC News, the host network, shared this week with both campaigns.

A copy of the rules was provided to the Associated Press on Thursday by a senior Trump campaign official on condition of anonymity ahead of the network’s announcement. The Harris campaign on Thursday insisted it was still discussing the muting of mics with ABC.

The parameters now in place for the Sept. 10 debate are essentially the same as they were for the June debate between Trump and President Joe Biden, a disastrous performance for the incumbent Democrat that fueled his exit from the campaign. It is the only debate that’s been firmly scheduled and could be the only time voters see Harris and Trump go head to head before the November general election.
