Leading is not hypothetical debating; it's about solving real problems.

What I always say with these things, when you`re trying to do comprehensive things like tax reform, there will be 20,000 lobbyists in Washington trying to work their will on that piece of legislation so, you know, people think it`s going to be a lot easier than it will end up being.

Countries make policies for themselves. And Donald Trump wants to make - that`s his policy.

Actually we're not hearing a lot about gas prices right now from constituents. And I think that reflects a growing understanding on the part of the public, that there really is very little that the government and politicians can do.

He [Donald Trump]wants to build the wall. It would be silly to say we`re going to - we`re going to create an army and we`re going to have Mexico pay for our border patrol, our border police. Clearly, that`s not going to happen.

If you destroy the credibility of those people or institutions that could undermine your own, you create an opportunity for your voice, however irresponsible or misleading it may be, to gain traction.

I was part of the gang of eight in the house in 2013 that was working on comprehensive immigration reform. We talked a lot about border security and what was effective and what was not. Walls are not effective when you`re out in the desert and you don`t need them.
