David Gergen: “I think it's unbecoming. It's sort of cheap and cheapens the presidency.”

If he had a receptive audience, and I will tell you, when everything -- when all the facts were to come out, it would be like Nixon and the tapes.

Sadly, you know, I think for a variety of reasons he should not. I just, I don't think either Trump or Biden should be running.

If he comes out and throws cold water on this, then I don't think it goes anywhere.

I think a lot of Americans do see it as disqualifying. And they're worried about it.
