People of my generation knew we needed to move beyond that, the racial division and segregation and unsustainable social relations, that were unfair to millions of people. But it didn't mean that we were going to become a big government liberal.

I think the leaders in all parties tend to adjust to reality. They just have to or they won't remain in office.

I would acknowledge that [Paul] Ryan has some really good ideas about things, and I think they'll get together, like taxes. Larry Kudlow, Stephen Moore, they've been supportive of Ryan's tax view and now they're very supportive of [Donald] Trump's. So I think that's got potential.

They [Republican voters] believe in a foreign policy that puts America first: Give me a break. And so a lot of our drift within our party has gotten away from that.

[Donald] Trump is underestimated greatly in terms of his understanding and comprehension of the great issues facing America. He understands trade. He's got businesses all over the world. He understands currency and how manipulating currency can be damaging to America.

Kissinger-type foreign policy is clearly, in my view, the proper tilt for us in the future, and he [Donald Trump] gets it. And some of our members, I guess, have been so deeply committed to the [George W.] Bush agenda, the neo-conservative agenda, that it's harder for them to acknowledge that. But I acknowledge it.

My advice is to listen and accept the will of the American people, the Republican voters. The Republican Party is the Republican voters, and Republican voters oppose these trade agreements more than Democrat voters do.
