The one thing that might have stopped San Bernardino, that might have stopped 9/11 would have been stricter controls on those who came here.

Everyone seems to have internalized the fact that you can say anything you want at a televised debate, and only a tiny fraction of the audience will ever see a fact-check. So why not claim the moon is square?

The essence of the conservative message should be we want a dynamic nation where anybody with nothing can achieve anything.

I appreciate the good work that senators in both parties have put into trying to fix our broken immigration system. There are some good elements in this proposal, especially increasing the resources and manpower to secure our border and also improving and streamlining legal immigration. However, I have deep concerns with the proposed path to citizenship. To allow those who came here illegally to be placed on such a path is both inconsistent with rule of law and profoundly unfair to the millions of legal immigrants who waited years, if not decades, to come to America legally.

We will stop the terrorist attacks before they occur because we will not be prisoners to political correctness. Rather, we will speak the truth. Border security is national security and we will not be admitting jihadists as refugees.

Donald Trump threatened to file a defamation suit against me for running a TV ad that consisted only entirely of his own words on national television. Now, that's really a remarkable theory, that it is defamation to show people what he said on national TV. I think the voters are smarter than that.

A path to citizenship for those who are here illegally in my view is unfair to those waiting sometimes a decades in line to come here.
