Just over a month before the White House election, the two US vice presidential candidates face off on the debate stage.

Ohio Republican Sen. J.D. Vance will square off against Minnesota’s Democratic Gov. Tim Walls in New York City on Tuesday night.

The debate comes three weeks after the same presidential showdown between Donald Trump, who chose Vance as his running mate, and Kamala Harris, who chose Walls.

The 90-minute clash will take place on Tuesday 1 October at 21:00 EDT (02:00 BST) at the CBS Broadcast Center in New York City.

It will be broadcast on CBS Network TV and streamed live on platforms where CBS News 24/7 and Paramount+ are accessible.

The forum will be moderated by CBS Evening News anchor Norah O’Donnell and Margaret Brennan, who hosts the network’s current affairs show Face the Nation.

There will be two breaks, four minutes each.

The rules for the vice presidential debate mirror those of the face-off between Trump and Harris last month, with one small difference: The microphones will be hot.

While CBS says it reserves the right to mute candidates’ microphones, they will continue even when it’s not a candidate’s turn to speak.

Both will stand, unlike the last three vice presidential debates in previous US election cycles, when the candidates sat.

Walls will stand behind the podium on the left side of the stage – screen right. Venus will stand opposite him.

Campaign aides will not be allowed to speak to the couple during the break. Nor will running mates be allowed to bring pre-written notes on stage.

Candidates will have two minutes to answer questions from the moderators. Second candidate will be given two minutes to answer. Each candidate will have one minute to rebut.

CBS says it’s up to Vance and Walz to fact-check each other’s statements, though “moderators will facilitate those opportunities” when rebutting.

There will be no live studio audience or opening statements.

Candidates will get two minutes for closing statements. Vance won the coin toss and chose the final word.

Walls is preparing as Venus with Transportation Secretary Pete Buttigieg.

He has been doing late night and weekend sessions and studying his competitor’s videos.

Vance is gearing up with Republican Congressman Tom Emmer, who represents Walls’ home state of Minnesota.

He is also meeting with his lawyer wife Osha Vance and senior Trump adviser Jason Miller.

It is likely that Vance will target Walls — a former public school teacher and football coach — who Republicans say has had heavy-handed Covid policies in Minnesota, including violating social distancing rules. Setting up a hotline to report those.

Vance may also criticize Walls for signing legislation last year that allows tampon dispensers to be placed in boys’ restrooms in public schools.

He could also accuse Walls of misrepresenting his military record. In August, Minnesota’s governor admitted he had “misspoken” when he said in 2018 that he had handled assault weapons “in a war” while advocating for stricter gun laws. Walls resigned from the National Guard before his unit deployed to Iraq.

The Minnesota governor will likely attack Vance for some of his past comments, including Some are calling out Democratic politicians. “A bunch of childless cat ladies with miserable lives”.

Walls could also go after the Ohio senator again and again. Defense of baseless stories About eating pets of immigrants in an Ohio town.

He may also try to embarrass Vance over his leaked messages from 2020 in which he said Trump had “totally failed to live up to his economic populism”.
