Imagine a legal immigration system that welcomes and celebrates those who come to achieve the American dream.

There's a real danger when people get distracted by peripheral issues. They get distracted by democracy building. They get distracted about military conflicts. We need to focus on defeating jihadism.

The immigrant experience of all of us is what makes us Americans, because we value in our DNA liberty and opportunity above all else.

What we saw with both Donald Trump and Marco Rubio, that their response, whenever you point to anything in their record, is just to yell, "Liar, liar, liar," and to get very personal and to make direct character attacks. And my approach, from the very beginning of this President's campaign, starting a year ago in 2015, is that I will not respond in kind. I do not intend to insult any of the candidates.

I get that the media wants us to play theater critics and critique every other proposal. What I`m focusing on are my own policy proposals.

We need a president who stands up, number one, and says, we will defeat ISIS. And number two, says the greatest national security threat facing America is a nuclear Iran.

The American free market system is the greatest engine for prosperity and opportunity that the world has ever seen. Freedom works.
