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

The FBI is unique in that it straddles both law enforcement and counterintelligence.

I have sort of a visceral aversion to the prominence of the either active duty, in the case of General McMaster, or retired general officers filling political, civilian positions.

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.

We're talking about nuclear war with North Korea. We're talking about Russia. Does it feel like the world has shifted? Are we all just in Donald Trump's reality show now?

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 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.
