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.

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

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.

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.

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.

The head of ISIS called for attacks during the season of Ramadan, which is what you have seen both in Orlando and now in Istanbul at the airport.
