“If President Trump makes of fun of his age or questions his mental state during a debate, Joe Biden has a response at the ready: He’ll challenge him to do push-ups on stage,” the Washington Post reports.
Said Biden: “I’d say, ‘C’mon Donald, c’mon man. How many push-ups do you want to do here, pal?’ I mean, jokingly. . . . C’mon, run with me, man.”
