David Gergen: “I think the chances are just gone up a lot, this going to get out of the Iranian agreement.”

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.

I think we're in an unsustainable path. It's compared to being in a car on the edge of a cliff, and middle of the night with it with a rainy and no headlights.

I think it's going to take something usually unexpected or a dramatic change in his health or a prison sentence to stop him.

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