Vance accepted the Oct. 1 debate the following day, while also proposing a debate for Sept. 18 on CNN. Michael Tyler, the communications director for Harris' campaign, told CBS News later that day that Walz will only participate in the Oct. 1 debate.

It will be the first time Kamala Harris' running mate, Tim Walz, and Donald Trump's running mate, JD Vance, face off.
