After having tempered attacks on Donald Trump following Saturday’s assassination attempt, President Joe Biden plunged back into campaign mode Monday, defending his decision to remain in the presidential race despite calls for him to exit.

In an interview with NBC News anchor Lester Holt, Biden at times grew combative and said he isn't leaving the race even though some Democratic leaders have expressed fears that he can't win.
“I’m old,” Biden said. “But I’m only three years older than Trump, No. 1. And No. 2, my mental acuity’s been pretty damn good. I’ve gotten more done than any president has in a long, long time in 3½ years. So I’m willing to be judged on that.”
