President Joe Biden joked that it's difficult acknowledging he's about to turn 80, but said he's physically and mentally capable of serving a potential second term in the White House.
Biden, who turns 80 on 20 November, said it’s “totally legitimate” for voters to question whether someone his age can manage the demanding stresses of the American presidency. Biden made the comment in response to a question about his age during an MSNBC interview that aired Sunday.
