Mr Biden, who turns 78 next month, would be the oldest ever president if elected to the White House on November 3. 

Earlier on Sunday, Mr Biden was forced to defend his physical and mental competence for the top job during a CBS 60 Minutes interview.

"All I can say to the American people is: watch me, see what I’ve done, see what I’m going to do. Look at me. Compare our physical and mental acuity. I’m happy to have that comparison," he told interviewer Norah O’Donnell.

Mr Trump also sat down with 60 Minutes, but walked out of the interview after claiming he was receiving a tougher grilling from the programme than Mr Biden. 

"I see Joe Biden, giving softball after softball. I’ve seen all of his interviews. He’s never been asked a question that’s hard," Mr Trump said.

Shortly afterwards, the irrate president said: "I think we have enough of an interview here… Let’s go."
