David Gergen: “If they've been lying to us on this, why are we to believe them on the collusion issue?”

For Donald Trump to go for a 24-plus hours without a word being said is an outrage in and of itself. This is a man who is seeking the nomination of a major political party, very likely to get it. And now look at the leadership he is…

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.

President of United States has not had a security briefing, or security briefing since October 2nd. I've never heard of any president, under any circumstances, come anywhere close to that, and been so derelict of the duty.

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