Former president Donald Trump’s campaign on Friday formally accepted Fox News’ invitation to participate in a vice-presidential debate against Kamala Harris this summer.

Fox requested the opportunity to host a debate between Vice President Harris and Trump’s future running mate on July 23, August 13, or sometime following the Republican and Democratic nominating conventions. The conservative media outlet also asked Virginia State University to allow the event to be held on its campus, considering the bipartisan Commission on Presidential Debates previously selected the historically black college or university (HBCU) to host a presidential debate in October.

However, that plan was scrapped after President Joe Biden’s campaign said it wanted debates outside the traditional format run by the commission. Instead, Trump and Biden mutually agreed on Wednesday to participate in two presidential debates — one hosted by CNN on June 27 and the other hosted by ABC News on September 10.

“On behalf of the future Vice President of the United States, who I have not yet chosen, we hereby accept the Fox Vice Presidential Debate, hopefully at Virginia State University, the first Historically Black College or University to host a Debate – Date to be determined,” Trump said on Truth Social Friday afternoon. “I urge Vice President Kamala Harris to agree to this. MAKE AMERICA GREAT AGAIN!”

Within two hours of Trump’s message, the Biden campaign rejected Fox’s vice-presidential debate invite and another proposal made by NBC News and Telemundo. Trump accepted the latter invite as well, but Biden was not keen on either offer. “The debate about debates is over,” a Biden campaign official told NBC News. “No more games.”

Harris accepted a debate proposal made by CBS News on Thursday. The Trump campaign has so far not accepted CBS’s invitation, which, like Fox, proposed dates for July 23 or August 13.

The news comes as Trump has yet to pick his vice-presidential candidate. Senator Tim Scott (R., S.C.), North Dakota governor Doug Burgum, Senator J.D. Vance (R., Ohio), Representative Byron Donalds (R., Fla.), Representative Elise Stefanik (R., N.Y.), and numerous others are on the rumored list of contenders. Burgum recently told the New York Post that over 50 people could be on Trump’s shortlist.

The presumptive Republican nominee said on Thursday there’s a “good chance” he’ll make the long-awaited announcement at the Republican National Convention, scheduled for July 15-18 in Milwaukee, Wis. The Democratic National Convention will take place from August 19-22 in Chicago, Ill.
