The U.S. affirms freedom of speech.[Vladimir] Putin is no friend of freedom of speech.

Once we affirm the goal of trying to make sure that you don't have jihadis infiltrating terrorist flows, we need to make sure we're doing it in a thoughtful way that's thinking about the 10 and 15 and 20 years long battle we're going to have against jihadists.

[Vladimir] Putin is an enemy of political dissent. The U.S. celebrates political dissent and the right for people to argue free from violence about places where our ideas are in conflict.

What happens in Senate fight club stays in Senate fight club.

We should vigorously debate policy differences. We have too much all-or-nothing in American politics.

In the American constitutional system of three different branches, conflict - and I mean that peaceful, vigorous debate - it's a feature of our system, not a bug. We need less all-or - winner-take-all politics.

I don't think we do a great job in America any more of distinguishing between campaigns and governance. We live in an environment that's all campaign all of the time and it's helpful, now that we've moved beyond a campaign and an election to get into a governance posture.
