Former Vice President Joe Biden, 75, said Tuesday it's not wrong for voters to consider the age of presidential candidates like him who might be considering a 2020 White House run.
"I think age is a totally legitimate thing to raise," Biden said during a speaker series at the Economic Club of Southwestern Michigan, CNN reported. "I think it's totally appropriate for people to look at me and say if I were to run for office again, 'Well, God darn you're old.' Well, chronologically I am old."
Biden made that comment after being asked about the possibility of imposing a mandatory retirement age for members of Congress and term limits for Justices on the Supreme Court.
The former senator from Delaware will be 77 when the campaign season for the presidential primary elections get started. While many Democrats want him to run, Biden hasn't yet said he will, and he said questions about his age would be fair game.

"Every voter is entitled to know exactly what kind of shape you're in. You owe it to them. It's a legitimate question and so I think age is relevant," he said.
Other Democratic presidential hopefuls also face questions surrounding their age.
Sen. Bernie Sanders, I-Vt., is 77 and Sen. Elizabeth Warren, D-Mass., is 69, and they are facing a possible pool of younger candidates such as 49-year-old Sen. Cory Booker, D-N.J., and Sen. Kamala Harris, D-Calif., who is 53.
President Trump is 72, and his doctors have said he has no health issues.
