America is at war. Our enemy is not violent extremism. It is not some unnamed malevolent force. It is radical Islamic terrorist.

We need to do whatever is necessary to utterly defeat ISIS....We're not using our overwhelming air power. We're not arming the Kurds. Those need to be the first steps. And then we need to put whatever ground power is needed to carry it out.

When you had a terrorist, you could only search a relatively narrow slice of numbers, primarily land lines.

We need to be focused on defeating radical Islamic terrorists.

I think the establishment donor class has begun to crumble. They`re searching for [Marco] Rubio, trying to get some momentum there. But the establishment in terms of the official elected leadership of the Republican Party, when you look at [Kevin] McCarthy, they`re starting to wrap theirselves around the idea of [Donald] Trump, holding back on an endorsement.

It's really remarkable to see two candidates,[Donald] Trump and [Marco] Rubio, making things up and putting things out for which there is no evidence and no basis.

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.
