The convention is slated for July in Milwaukee, Wisconsin, a key battleground state in the 2024 election that President Trump won in 2016 but narrowly lost to President Joe Biden in 2020.

"That's probably a pretty good chance, I would say," President Trump said in an interview with Scripps News released on Thursday, in reference to whether or not he would announce his pick at the convention. "I don't say anything is 100 percent, but you're getting pretty close. I'll be doing it in Milwaukee."

President Trump in 2016 announced his then-vice presidential pick Mike Pence just three days prior to the Republican Convention that summer in Cleveland, Ohio.

The last time a presumptive Republican nominee for president waited until the convention to announce their vice presidential running mate was in 1988 when then-Vice President George H.W. Bush announced his running mate Dan Quayle on the third day of the party's August convention.

The last time a presumptive Democratic nominee for president waited until the convention to announce their vice presidential running mate was in 1976 when Jimmy Carter announced Walter Mondale as his pick on the last night of the party's July convention.

Since the 1968 presidential election, the earliest a presumptive nominee announced their running mate was in 2004 when Democratic nominee John Kerry announced John Edwards as his running mate 20 days prior to the convention, while on the GOP side, Mitt Romney announced his running mate Paul Ryan 16 days prior to the 2012 Republican convention.
