I have spent almost my entire adult life fighting to defend the religious liberty of every American to follow his or her faith and live according to his conscience.

We need a president who understands the first obligation of the commander-in-chief is to keep America safe. If I am elected president, we will hunt down and kill the terrorists. We will utterly destroy ISIS.

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.

Donald [Trump] is a charming person. He can be fun. He can make you laugh. But he can turn on you. And get nasty and personal and vicious.

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

I will happily support anything that protects life.

I think primary voters have a right to know. And Donald's Trump excuse of it that he's being audited, look, that makes it even more important for him to release his taxes, so that voters can see if there is - Mitt Romney suggested there could be a bombshell there. I don't know if there is or not. But Donald is hiding them from the voters, and I think he owes candor to the voters.
