July 5 (UPI) -- President Joe Biden on Friday held a campaign rally in the battleground state of Wisconsin ahead of his interview with ABC News and amid increased pressure for him to withdraw from the race.

Addressing a crowd of supporters enthusiastically chanting in Madison, "Let's go, Joe!" Biden didn't shy from the controversy of his debate performance but doubled down on his commitment to continue running and beat Donald Trump in November.

"I can't say it was my best performance, but since then there's been a lot of speculation -- what's Joe going to do?" he said. "Well here's my answer: I am running, and I'm going to win again."

The 81-year-old president also brushed aside concerns about his age by emphasizing his accomplishments.
