Pence pressed on Biden's age, presidential fitness tests
Pence was pressed by moderators if presidents should have to pass a mental and physical test to serve, invoking President Joe Biden's age.
Pence, who is 64, initially joked that "it might be a good idea to have everybody in Washington" pass one.
He then took a serious tone, saying, "No, the American people can make those judgments."
He appeared to take a swipe at Ramaswamy, the youngest candidate on stage, stating the nation doesn't need a president who is too young either.
