I think the presidency is much too serious a thing to just play politics with.

It's perfectly legal in this country to change your mind. But when you're a governor, you have to admit it. You can't hide behind parliamentary tricks. That's the difference, and that's the kind of leader we need in the White House. Stop the Washington bull and let's get things done.

We need to focus our attention on Iran, because if you miss Iran, you are not going to get ISIS. The two are inextricably connected because one causes the other.

Governor Romney has been a great success in business. He has been a great success as executive, as governor of Massachusetts. I think that's the kind of guy we want in the White House.

Be careful about anybody who's running for president who's going to tell you that they're going to build a wall across the entire southern border. It's not going to happen. It is the wrong message to send. And it's not going to be effective.

The message [of Donald Trump] is that that type of thing happening. Let's focus on what happened.What happened was the murder, the murder of this person pushing a stroller, it's unacceptable in an American city to continue to have this level of violence and the level of violence in Chicago is unacceptable.

We cannot promote someone to Commander-in-Chief who has made the world a more violent and dangerous place with every bad judgment Hillary Clinton has made.
