I'm a constitutionalist. You know, does faith matter to me? Sure. But the beauty of the Constitution, the beauty of the First Amendment, it protects everyone's faith.

One of the most troubling aspects of the Rubio-Schumer Gang of Eight Bill was that it gave President [Barack] Obama blanket authority to admit refugees, including Syrian refugees without mandating any background checks whatsoever. Now we've seen what happened in San Bernardino. When you are letting people in, when the FBI can't vet them, it puts American citizens at risk.

The front line with ISIS isn't just in Iraq and Syria, it's in Kennedy Airport and the Rio Grande. Border security is national security.

You can use data wrong. It's just like polling. There have been a lot of politicians who go conduct a poll to figure out what they believe.

A very good friend of mine spent a fair amount of time doing postmortems and met with a number of the senior folks on the Romney campaign and they spent, what was it, $140, $160 million on data. And this friend of mine, who is a very sharp thinker, asked a series of questions, but the most important one he asked, he said, "What decisions did you make differently because of the data?" And he's coming from the private equity world where he wants to know, OK, and the answer from virtually every single senior Romney person was "nothing."

We are not any safer through the bulk collection of all Americans' records.
