Since Harris became the de facto Democratic nominee following President Biden's exit from the race, Vance has intensified his criticism of both Harris and her running mate, Governor Tim Walz (D-MN).

He has repeatedly pointed out that Harris, as the current vice president, could already be addressing issues she promises to tackle "on day one" of a potential Harris-Walz administration.

Vance has also taken aim at Harris's limited engagement with the press. In one instance, he approached reporters waiting for Harris, jokingly stating he was examining Air Force Two as it might soon be his aircraft. He offered to take questions, drawing a contrast with Harris's reluctance to do so.

After more than a month as the presumptive nominee, Harris has agreed to a pre-taped interview with CNN's Dana Bash, scheduled to air on Thursday. Governor Walz is expected to join her for this rare media appearance.
