"I took two cognitive tests, I aced them," Trump said. "He took none, I'd like to see him take one, just one." 

"I just won two club championships, not even senior, two regular club championships. To do that, you have to be quite smart. And you have to be able to hit the ball a long way," the former president continued.

Biden defended his age, saying he "spent half my career being criticized about being the youngest person in politics. I was the second-youngest person ever elected to the United States Senate, and now I’m the oldest. This guy is three years younger and a lot less competent." 

"Look, I'd be happy to have a driving contest with him," Biden said.
