Of strong importance to me is the defense of minority rights, not just racial minorities, but ideological and religious minorities.

There's 150,000 students here from the Middle East. If 40% of them have overstayed their visa, don't we need to know where they are, what they're doing, are they obeying our rules?

If you give up your rights now, don’t expect to get them back.

I think that by arming the allies of ISIS, the Islamic rebels against [Bashar] Assad, that we created a safe space or made that space bigger for ISIS to grow.

I would have handled it differently than the mayor of Baltimore, that's for sure. I think it's a mistake to say, hey, guys, you can pillage the city for a while and we'll let that go, and we'll be sort of standing back.

I think Saudi Arabia often finances radical Islam and the teaching of hatred to the West and hatred of Americans. I think it is important that we know that. It's important that we know that there is a threat within and a threat without. I think we can stop it with more aggressive use of actual constitutional tools.
