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.

Obviously, what's happening in China right now is crucial, in the party congress, which as someone said has anointed a new emperor of China in President Xi.

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 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.

Trump is very skillful at identifying - even if he can't quite get it clear, or precisely describe it - but that's what he wants to do, is always have something to use against people, even if it's distorted.
