President Trump and his administration are right to be concerned about national security, but it's unacceptable when even legal permanent residents are being detained or turned away at airports and ports of entry.

I think the Respublican party's lost its way. We have given into nativism and protectionism. And I think that, if we're going to be a governing party in the future, and a majority party, we have got to go back to traditional conservatism, limited government, economic freedom, individual responsibility, respect for free trade. Those are the principles that made us who we are.

The impulse to scapegoat and belittle threatens to turn us into a fearful, backward-looking people. In the case of the Republican Party, those things also threaten to turn us into a fearful, backward-looking minority party.
