I was the chairman of the Budget Committee and the lead architect the last time it happened in Washington, and when we did it we had great economic growth, we cut taxes, and we had a big surplus.

I was not in favor of U.S. troops in Lebanon. And I voted against it.

Frankly, we should publicly increase them [ anti-Russian sanctions ].

I was a member of the Armed Services Committee for 18 years. I spent a big chunk of my life studying national security issues and our role in the world.

It's an individual morality in values that matters in these companies [like Wells Fargo]. I mean, they ought to clean house. And they ought to figure out how to claw back all this money. That is a given. In terms of additional laws, there are reasonable approaches to this, but I'd have to see what they are. I'm not a federal lawmaker.

I just don't see anybody that's particularly interested in fixing that.

I've been frankly very surprised at the intensity of our differences [with Russia]. I mean, between what appears to be hacking of our political system to the aggressive use of nukes on the borders, to these atrocities in Syria and their warnings. I've been very, very surprised at the intensity of all this.
