It's one thing for someone to travel over to Syria and Iraq and come back. But, boy, it's a lot easier if they activate someone who's already here.

We are ramping up security in the United States but also looking at visa applicants, visa waiver applicants - and looking at travel manifests on the airplanes trying to come into the United States.

There's a conspiracy going on online every day between these top U.K. individuals within ISIS leadership out of Syria.

The sad fact is, because we've had a failed policy and failed leadership, now we're having to rely on Russians and the Iranians to go into Syria to fight and destroy ISIS.

Without - you know, good intelligence stops plots against the homeland. Without that intelligence, we cannot effectively stop it.

I think there is a failure in foreign policy. And you have to acknowledge that under Barack Obama, Hillary Clinton was the architect of that foreign policy. Whether it was malevolent or not, I don't know.
