We did drive them [Iran] to the negotiating table. And my successor, John Kerry, and President [Barack] Obama got a deal that put a lid on Iran's nuclear program without firing a single shot. That's diplomacy. That's coalition-building. That's working with other nations.

We have to build a political consensus and that requires people to give up a little bit of their own turf in order to create this common ground.

When you have three out of the four largest banks in America today, bigger than they were - significantly bigger than when we bailed them out because they were too big to fail, I think if Teddy Roosevelt were alive today, a good Republican by the way, what he would say is: Break them up; they are too powerful economically; they are too powerful politically.

I believe I am a work horse. I believe that that is what our country needs. We need a president who will roll up our sleeves collectively as a nation and tackle the problems that we confront.
