David Gergen: “I think that's unfair to the people involved.”

You can't out-Nixon Nixon very easily, but Donald Trump has.

I don't think Trump is out of the woods, even though his poll numbers are not only staying up, they have actually been strengthened some.

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.

It's very, very big. Not legally, but politically, it's a very, very big deal.
