Presidential candidate Joe Biden is done taking criticism for his age, saying that he’ll challenge Trump to a push-up contest if he raises the issue at a debate. “I’d say, ‘C’mon Donald, c’mon man. How many push-ups do you want to do here, pal?’” Biden said on MSNBC’s Morning Joe. “I mean, jokingly. . . . C’mon, run with me, man.” The Democratic presidential candidate added that when he participates in parades, he typically runs along the route, most recently during a July 4 parade. Biden is 76 years old, while Trump is 73. In 2018, Biden told a crowd “I’ve been in a lot of locker rooms my whole life. I’m a pretty damn good athlete.”
