There's a host of difficult issues here, and that's why when you mentioned at the top of the show that the committees were looking at this, that's where I think we should be going.

The intelligence community, in particular the FBI, have been sounding alarms about this for more than a year. So to argue that suddenly we have to do this because of the San Bernardino case doesn't really pass the straight-face test. I mean, they've been talking about this. And to say, well, it will only apply to this case, that just - that doesn't wash. This is a major piece of public policy.

The idea of some contact of Donald Trump's office with the Russians to try to find areas of common ground is not irrational or unusual. The question is: Were you doing it in an appropriate way and through proper channels?

The only, the only possibility would be if the Republicans are in the majority and they can offer me something that would be especially advantageous to Maine. Somebody said, 'You may be a committee chair.' I don't think so. I don't think anybody would want me that much.

Well, first let's say that the fundamental responsibility of any government is national security - in the preamble to the Constitution, provide for the common defense and insure domestic tranquility.

James Comey had nine interactions with Bob Mueller after the Donald Trump's election. And in none of those, Comey testified, did he express any interest, concern, about what the Russians did, how they did it, how do we prevent it. He continuously has in fact denigrated the whole idea and dismissed that it was the Russians, and apparently hasn't yet accepted the 100-percent consensus of everybody that knows about this that this was a conscious and deliberate effort on their part to attack our democracy.

I haven't seen - I haven't heard the arguments that would make that case. And I haven't seen a proposal yet that satisfies the objections. The problem is, you create a key like this, and it can't - it's hard to say that it's going to be hidden. And then it becomes used both by our government in multiple cases, but also it could get out as far as hackers are concerned or other countries.
