Vance and Walz Will Debate Standing Up, in a Rarity for V.P. Clashes

Gov. Tim Walz of Minnesota and Senator JD Vance of Ohio will stand behind lecterns for their debate next week, according to three people briefed on the plans, the first time since 2008 that the vice-presidential candidates have not been sitting for a debate.

The two candidates and CBS News, which is hosting the debate at its New York studios, are still in negotiations on all of the rules, but the network and the two campaigns have agreed that Mr. Walz and Mr. Vance will be standing, according to the three people, who insisted on anonymity because they were not authorized to discuss the preparations.

The rules are expected to be broadly similar to those for the presidential debate two weeks ago between Vice President Kamala Harris and former President Donald J. Trump.
