WATCH: Biden responds after being asked “Have you been tested for some degree of cognitive decline?”

During a press conference in Wilmington, DE, Joe Biden was asked by Fox News reported Doug McKelway “have you been tested for some degree of cognitive decline.”

McKelway also prefaced his question by saying “I’m 65, I don’t have recollection I used to have. I forget my train of thought from time to time. You’ve got 12 years on me.

Biden responded ““I’ve been tested, I’m constantly tested,” Biden said defiantly. He then continued “Look, all you’ve got to do is watch me and I can hardly wait to compare my cognitive capability to the cognitive capability of the man I’m running against.”
