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.

I think it's important to note that after the airstrikes began in Iraq and Syria, ISIS began a very aggressive social media campaign calling for these types of attacks, these lone wolf attacks.

For me, the biggest thing is someone who's kind. I'm not into the bad-boy thing.

I think Syria is now the training ground for the world... These rebel forces are more of a threat than anything.

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.
