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.

The only thing I heard Speaker [Paul] Ryan say that made sense was, we actually really need to look at this and see what makes sense and what doesn`t, because electronic detection in those kind of - and drones and other types of border protecting devices seem to be much more effective in certain places.

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.

I don`t think this wall [Donald Trump wants to build], having the - there`s no way to force them to, but expecting the Mexicans to pay for it doesn`t make any sense either.

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.

When your voice contradicts reality and truth, the only way to create space for it is to discredit reality and truth.
