President Donald Trump says he feels "young" and "vibrant" at age 72 and thinks he can beat 76-year-old Joe Biden "easily."
A reporter asked Trump at the White House on Friday how old is too old to be president of the United States.
Trump said: "I just feel like a young man. I'm so young. I can't believe it. ... I'm a young vibrant man."
Then he smiled and said he's not sure about Democratic presidential contender Biden, the second-oldest contender in the race behind Bernie Sanders.
Trump said: "I look at Joe. I don't know about him."
Biden, in an interview on ABC's "The View," joked in response that if Trump "looks young and vibrant compared to me, I should probably go home."
