I think Trump's presidency represents a completely different model than what we're used to. And I think to your point, yes, he is a great communicator, you know? He uses Twitter to great effect. I just wish he could stick more to the truth, because it's a very effective way of communicating directly with the American people.

The Russians succeeded, I believe, beyond their wildest expectations. Their first objective in the election was to sow discontent, discord, and disruption in our political life, and they have succeeded to a fare-thee-well. They have accelerated, amplified the polarization and the divisiveness in this country and they've undermined our democratic system. They wanted to create doubt in the minds of the public about our government and about our system; and they succeeded to a fare-thee-well. They've been emboldened and they will continue to do this.

Impeachment is our system's last resort for someone who treats himself or herself as above the law, the most relevant thing is whether this president, by his recent course of action, on top of his violations of the foreign corruption or emoluments clause, this president has shone that he cannot be trusted to remain within the law and our constitution's last resort for situations of that kind is to get the person out of office.

We have lots of challenges around the world, and I have no doubt the intelligence community will continue to watch them, monitor them, and report on them. The issue is, with all of our other distractions here in Washington, particularly, will the appropriate attention be paid to each one of these issues?

I think, as a professional courtesy, when the president asks you to dinner, you go.

We had a general awareness, for example, of Russian use of social media - Facebook ads, use of Twitter, fake news implants - we had a general understanding of that. But now, as time has elapsed and time has gone on, I've certainly learned a lot more about the depth and breadth of what the Russians were about.

I don't think the intelligence community itself institutionally is losing its focus; it will continue to do its job; continue to be vigilant on all issues that are besetting us. I think the greater danger is just the preoccupation of the policy community, and how much attention they pay to what the intelligence community is telling them.
