Republican vice presidential nominee, Sen. JD Vance, R-Ohio, and Democratic vice presidential candidate, Minnesota Gov. Tim Walz, will debate Tuesday with unmuted microphones, a departure from the rules during the first two presidential debates, debate host CBS News announced Friday.

The candidates will have two minutes to answer questions during the 90-minute debate, two minutes to respond and one minute for additional rebuttals. There will be no opening statements and the candidates will each have two minutes for closing statements. Vance won the coin toss to give the final word. Candidates will not be given questions in advance, nor will they be allowed to interact with campaign staff or have pre-written notes during the debate.

Tuesday, Oct. 1 at 9 p.m. ET on CBS News from the network’s studios in Philadelphia, without a live audience. The debate will be broadcast by all CBS local affiliates, simulcast by most major networks and available for live-streaming on the websites of most major news networks.

“CBS Evening News” anchor Norah O’Donnell and “Face the Nation” moderator and chief foreign affairs correspondent Margaret Brennan.

Neither an agreement nor a proposal for a second debate has been made public.

Harris immediately challenged Trump to a rematch at the conclusion of their first debate earlier this month, but Trump has said he won’t debate her again, insisting Harris only wants a rematch because he “won” the first faceoff.

More Americans view Walz favorably (39% vs. 34%) than they do Vance, and more say Walz is qualified to serve as president if necessary than Vance (35% versus 30%), according to a September Pew Research survey of U.S. adults.

Vance, a former Marine and Iraq war veteran, seized on criticism of Walz’s military record soon after Walz’s entrance into the race, accusing him of “stolen valor.” Walz, for years, has faced allegations from some of his fellow guardsmen of retiring from the National Guard to avoid being deployed to Iraq, though others who served alongside Walz have defended him and said he had discussed retiring to run for Congress months before his unit’s deployment was announced. Republicans have labeled both Harris and Vance as far-left, and have coined the nickname “Tampon Tim” for Walz, in reference to a law he signed as governor requiring menstrual products be available in restrooms used by students in grades 4-12 in public schools to ensure transgender students have access to them.

Vance has faced a string of controversies since joining Trump’s ticket. Resurfaced comments he made in 2021 about “childless cat ladies” running the Democratic Party drew widespread scrutiny, and he is widely credited with amplifying the baseless claim that Haitian migrants in Springfield, Ohio, were abducting and eating residents’ house pets, leading to increased threats of violence in Springfield. Walz has repeatedly referred to Vance and Trump as “weird” throughout the summer, popularizing the attack line among Democrats. And Harris’ campaign has cited Vance’s prior public comments in support of making abortion illegal nationwide, as Trump and Vance seek to distance themselves from the idea.

Trump tapped Vance as his running mate in July at the start of the Republican National Convention. Harris chose Walz about three weeks after launching her own campaign on July 21 when President Joe Biden dropped out of the race. Both hail from the Midwest and are relatively new to the national political scene. Vance was first elected to public office in the 2022 midterm, and Walz was relatively unknown to voters on a national level prior to him joining Harris’ ticket.
