The president sets the tone. He creates the atmosphere, and that can be enlightened, progressive, or it can be intimidating, depending on what the president's agenda is. I think the other dimension of this that I worry about is impacts overseas with friends and allies, many of whom are very, very concerned about America's position in the world and whether or not it's going to continue its leadership, which has been the prevalent condition since World War II.

First Russians objective was - as I said earlier - to sow discord, discontent, disruption. And their next objective was - because of the very strong personal animus that Putin himself had for both Clintons, both President Clinton and Secretary Clinton - and he particularly held her responsible for what he felt was an attempted color revolution in 2011 to attempt to overturn him. So, he had very strong hatred - personal hatred - towards her, and that kind of led him to - if I'm opposed to her, who am I going to favor?

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.

What I said was, ‘the NSA does not voyeuristically pore through U.S. citizens’ e-mails.’ I stand by that.

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.

When I visited North Korea in November 2014, is that Kim Jong-un is not merely the head of state of the DPRK - the Democratic People's Republic of Korea, North Korea - he's also their deity. So, when you insult him as the head of state, you're also insulting the deity, which of course the regime plays to a fare-thee-well to the domestic audience there.

We must remain mindful of the potential impact of over-correcting the authorizations of the intelligence community.
