I'm in charge of the State Department's 60,000-plus people all over the world, 275 posts.

I'm thrilled the president [Barack Obama] has endorsed me. We started off as fierce competitors, and we've ended up as true friends and partners and worked together on so many important issues.

We know that russians are deeply engaged in supporting Assad because they want to have a place in the Middle East. They have a naval base, they have an air base in Syria.

If you're a realist, you know that people have different roles to play in politics, economics, and this is an important role, but I do think that there has to be an understanding of how what happens here on Wall Street has such broad consequences not just for the domestic but the global economy, so more thought has to be given to the process and transactions and regulations so that we don't kill or maim what works, but we concentrate on the most effective way of moving forward with the brainpower and the financial power that exists here.

I think if we work together, if we overcome the divisiveness that sometimes sets Americans against one another, and instead we make some big goals, there's nothing in my opinion that America can't do.

We can have enough clean energy to power every home.

If I remembered when people said mean things about me, I would never speak to the media again.
