Speaking to ABC News on Friday, Mr Biden also declined to
take a cognitive test and make the results public in order to reassure voters
he is fit to serve another term.
"I have a cognitive test every single day. Every day I
have that test - everything I do [is a test]," he told George
Stephanopoulos.
The 81-year-old once again pushed back on the idea, aired
by some Democratic officials and donors, that he should stand aside for a
younger alternative following his disastrous debate with Donald Trump last
week.
Throughout the interview, Mr Stephanopoulos pressed the
president, external on his capacity to serve another term, asking Mr Biden if
he was in denial about his health and ability to win.
“I don’t think anybody’s more qualified to be president or
win this race than me," Mr Biden said, blaming his poor performance last
week on exhaustion and a "bad cold".
The president answered questions more clearly than he did
on the debate stage last week, but his voice again sounded weak and
occasionally hoarse.
It was a sharp contrast to his performance at a rally in
Madison, Wisconsin, on Friday, where an energised Mr Biden acknowledged his
disastrous performance in last week's CNN debate. "Ever since then,
there’s been a lot of speculation. What’s Joe going to do?” he told the crowd.
“Here’s my answer. I am running and going to win again,” Mr
Biden said, as supporters in the crucial battleground state cheered his name.
