I would love having the job of president because I know how to do it. I know what the country needs.

I think when you look at the letters that I get, a lot of people are worried that maybe they wouldn't have a place in Donald Trump's America.

Donald Trump used undocumented labor to build the Trump Tower. He underpaid undocumented workers, and when they complained, he basically said what a lot of employers do: "You complain, I'll get you deported."

President Lincoln was trying to convince some people, he used some arguments, convincing other people, he used other arguments. That was a great - I thought a great display of presidential leadership.

We need to have a resolve that will bring the world together to root out the kind of radical jihadist ideology that motivates organizations like ISIS, a barbaric, ruthless, violent jihadist, terrorist group.

We've got this arc of instability from North Africa to South Asia, and we have to pay close attention to it. And we have to build coalitions, something that I did to take on the Iranian nuclear program, and what I will do as president to make sure that we defeat these terrorist networks.

American leadership is essential.
