According to CBS News, microphones will not be muted during the vice presidential debate

CBS News on Friday announced rules for the vice presidential debate taking place Tuesday night between Democratic vice presidential nominee Gov. Tim Walz and Republican vice presidential nominee Sen. JD Vance.

Notably, the station said that contestants’ microphones would not be muted, but clarified in a press release that it “reserves the right to turn off contestants’ microphones.”

This is a departure from CNN’s presidential debate in June and ABC News’ presidential debate earlier this month, where microphones were muted unless it was the candidate’s turn to speak.

CBS News also said that Vance won a virtual coin toss for the right to determine the order in which each candidate makes their closing statement, and he decided to speak after Walz. (There will be no opening statement.)

Walz will be on stage left (the right side of the screen for the audience) and Vance will be on stage right. Walz is also introduced first because he belongs to the incumbent president’s party.

Candidates are not allowed to have any notes or props with them.

The debate, to be held in New York City and moderated by CBS journalists Norah O’Donnell and Margaret Brennan, is scheduled to be 90 minutes long and will take place without a studio audience, similar to CNN and ABC News debates.

Each candidate has two minutes to answer a question and their opponent then has two minutes to respond. The candidates then have one minute each to provide further rebuttals, and CBS News said the moderators may give the candidates another minute to finish a topic.

The debate is expected to be the only time the vice presidential candidates will face off on stage, and it comes just over a month before the presidential election.

Both candidates have prepared for the crucial event.

Vance’s preparations for the debate included sessions at his home in Cincinnati and online sessions with his team and with Jason Miller, a senior adviser for former President Donald Trump’s campaign, a source told ABC News. And the Ohio senator is turning to Minnesota Rep. Tom Emmer to help him with debate rehearsals by playing waltz, sources familiar with the plans told ABC News.

Meanwhile, Walz has held mock debates, sources told ABC News, with Transportation Secretary Pete Buttigieg acting in his personal capacity as Vance’s representative, and held policy sessions with his own longtime advisers, Biden White House alums and members of the Harris -Walz campaign team.
