How to Watch the Vance-Walz Vice-Presidential Debate

Gov. Tim Walz of Minnesota and Senator JD Vance of Ohio will face off on Tuesday in the only scheduled vice-presidential debate, convening three weeks after their running mates, Vice President Kamala Harris and former President Donald J. Trump, sparred in Philadelphia.

Mr. Walz has been preparing for the debate in Minneapolis, where Transportation Secretary Pete Buttigieg is serving as an informal stand-in for Mr. Vance, according to several people with knowledge of the process. Mr. Vance, who has been preparing in Ohio, has had Representative Tom Emmer of Minnesota standing in for Mr. Walz in his rehearsals.

The debate is scheduled for 9 p.m. Eastern on Tuesday, Oct. 1. It is expected to last 90 minutes.

The debate will be held in New York City at the CBS Broadcast Center, the network’s production studios.

The New York Times will stream the debate alongside commentary and analysis from our reporters in real time.

CBS News will broadcast the debate in its entirety and stream it on CBS News 24/7 and Paramount+. Other television networks will be able to carry a simulcast of the event.

The event will be moderated by Norah O’Donnell, the anchor of “CBS Evening News,” and Margaret Brennan, who moderates CBS’s weekend show “Face the Nation.”

CBS has yet to announce the rules of the debate, or whether the vice-presidential nominees will appear in front of an in-person audience. At the Sept. 10 presidential debate, which was hosted by ABC News, there was no audience, and Ms. Harris’s and Mr. Trump’s microphones were muted when it was not their turn to speak.

It’s possible, but unlikely. Ms. Harris, who according to polling was widely seen to have won her first debate with Mr. Trump, accepted an invitation from CNN to debate on Oct. 23.
