Stephen Colbert said Joe Biden debated 'as well as Abraham Lincoln, if you dug him up right now'

• "The Late Show" host Stephen Colbert has thoughts on the bad Biden debate.
• "I think that Biden debated as well as Abraham Lincoln, if you dug him up right now," he joked.

In a monologue laden with wisecracks, "The Late Show" host Stephen Colbert gave his take on President Joe Biden's abysmal debate performance.

In a clip of the show posted on his Instagram on Monday, he said that Biden is a "great president" and it was a shame that "Biden's shakiness allowed Trump to get away with 90 minutes of lies, racism and weird golf brags."

Colbert said Biden's bad showing has become the reason "why a lot of people are saying this was the worst debate performance of all time."

"But I don't think that's fair. I think that Biden debated as well as Abraham Lincoln, if you dug him up right now," he joked.

Colbert also talked about Biden's mental capabilities, which have Democrats and their donors wondering if he is fit to run for reelection.

He said: "So, should he stay? Should he go? Who am I to recommend? I don't know what's going on in Joe Biden's mind."

"Something I apparently have in common with Joe Biden," he added, drawing laughter from the audience.

Biden is facing mounting pressure from a growing number of rich Democrats who are pulling back their support for Biden over concerns for his fitness to run, such as Netflix cofounder Reed Hastings and Disney's co-founder Abigail Disney.

But the president has declared that he will stay in the race despite pressure on him to quit.

Anonymous sources told Politico that during a Zoom call with his staffers on Wednesday, he said: "Let me say this as clearly as I possibly can — as simply and straightforward as I can: I am running."

He's also said that only the "Lord Almighty" could make him step down.

Representatives for Biden and Colbert didn't immediately respond to requests for comment sent outside regular business hours.
