I liked Donald's Trump speech on foreign policy. What he's showing is that his fundamental views are solid, and that there's an intellectual basis for this, an economic basis for what he's saying, and that can lead him to victory.

I didn't endorse Donald Trump but I thanked him for coming, thanked him for raising issues that were important, thanked him for talking about immigration and considering the views that we had worked on for a number of years, on what a good immigration policy should be.

Those policies - more taxes, more regulation, more debt, more spending, more government - will make American worse. It just will, in my view.

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.
