Iran's nuclearization is the greatest single national security threat America faces.

At the end of the day after a few speeches and a lot of campaign stops, I'm more energized than drained.

America can compete with anyone in the world as long as the playing field is level. China's been cheating over the years. One by holding down the value of their currency. Number two, by stealing our intellectual property; our designs, our patents, our technology. We will have to have people play on a fair basis.

Freedom. Freedom of religion. Freedom to speak their mind. Freedom to build a life. And yes, freedom to build a business. With their own hands. This is the essence of the American experience.

I like being able to fire people.

I know what it's like to start a business. I know how extra ordinarily difficult it is to build something from nothing. I know how government kills jobs and, yes, I know how it can help from time- to-time.

We're not going to let our campaign be dictated by fact checkers.
