I don't measure success by how many buildings have my name on it.

ISIS have to be defeated. They have to be defeated militarily. How are we going to do that if we continue to weaken our military?

Oftentimes, your choices are down to two less than ideal outcomes, but you have to choose which one is the best one for the country. I personally believe he continues to struggle to articulate that.

We will have to work around the world with less than ideal governments. The government in Saudi Arabia is not a democracy, but we will have to work with them. The government in Jordan is not perfect, but we will have to work with them. But anti-American dictators like [Bashar] Assad, who help Hezbollah, who helped get those IEDs into Iraq, if they go, I will not shed a tear.

Leadership can not be measured in a poll or even in the result of an election. It can only be truly seen with the benefit of time. From the perspective of 20 years, not 20 days.

I challenge the Republican nominees and all Republicans to not just be the anti-illegal immigration party. That's not who we are and that's not who we should be we should be the pro-legal immigration party.

ISIS is a radical jihadist group that is increasingly sophisticated in its ability, for example, to radicalize American citizens, in its inability to exploit loopholes in our legal immigration system, in its ability to capture and hold territory in the Middle East, as I outlined earlier, in multiple countries.
