Former President Joe Biden took a swipe at CNN anchor Jake Tapper and his co-author Alex Thompson after being asked about allegations in the book, “Original Sin,” which talks about the mental and physical decline of the octogenarian when he was in the White House.

He was at a Memorial Day even in his home state of Delaware on Friday when he was asked by a reporter about what was said in the book.

“There’s also been a lot of discussion recently about your mental and physical capabilities while you were in office,” the reporter said.

“You can see that I’m mentally incompetent and I can’t walk,” the former president said as a quip, but what many people believe is accurate, before he said “and I can beat the hell out of both of them” in reference to the two authors.

“Do you want to reply to any of those reports, and also to the fact that there are some Democrats who are now questioning whether you should have run for reelection in the first place?” the reporter said.

“Why didn’t they run against me then? Because I’d have beaten them,” the former president said.

The reporter then asked the former president if he had “any regrets?”

“No, I don’t have any regrets. Look, there’s a lot going on, and I think we’re in a really difficult moment—not only in American history but in world history. I think we’re in one of those inflection points in history where the decisions we make in the next little bit are going to determine what things look like for the next 20 years. I’ve been talking about that for a long time. And I’m very proud,” Biden said.

“I’d put my record as president against any president at all. You notice that 12 of the 10 leading presidential historians rated me pretty good up on that list—and the guy I ran against, I rated him last. So, we’ll see,” he said.
