Tim Walz has agreed to an Oct. 1 vice presidential debate on CBS against his Republican rival, JD Vance, who has not yet responded to the invitation.

CBS News announced Wednesday that it had invited both Walz and Vance to a debate in New York City, and offered four date options.

Within minutes of the invitation, Walz posted on the social media platform X, “See you on October 1, JD.” Walz spent Wednesday in Denver at a private fundraiser, where he reportedly raised $3 million. He was headed to New England next for fundraisers in Boston and Rhode Island.

Vice President Kamala Harris and former President Trump are set to face each other at the first presidential debate between the two rivals on Sept. 10. Trump has proposed two more debates.
