I don't think we should be engaged in nation-building. It's not our job to turn foreign nations into democratic utopias, to try to turn Iraq into Switzerland. It is the military's job to hunt down and kill our enemies, to kill ISIS before they murder American citizens and they wage jihad.

I introduced bill saying we need more security, we need more scrutiny. Once again, Marco [Rubio] opposed this. So Marco can't have it both ways. He thinks he wants to be this, "Oh, I'm great and strong on national defense." But he's the weakest of all the candidates on immigration. He is the one for an open border that is leaving us defenseless.

We don't have a system that knocks on doors of every person in America.

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.

The USA Freedom Act expands that so now we have cell phones, now we have Internet phones, now we have the phones that terrorists are likely to use and the focus of law enforcement is on targeting the bad guys.

If you want someone to grab a beer with, I may not be that guy. But if you want someone to drive you home, I will get the job done and I will get you home.

The proper way to make policy changes is for you to convince your fellow citizens that there is a better policy outcome than the current one. And then in state legislatures, for those state legislatures to vote that change.
