Barack Obama is an incredibly intelligent, thoughtful, decisive person in pursuing the agenda he sets.

When I was secretary of state, I had to be responsible for getting a nuclear arms reduction treaty with Russia through the Senate. We needed, I think, 13 Republican votes to get to 67. I started working in the summer making just endless phone calls, meetings, bringing experts to talk to Republicans, and then we finally got it done at the end of the year 2010. So I'm excited to roll up my sleeves and get into the business of solving problems and making progress together.

We do have to worry about North Korea. They continue to develop their nuclear weapons capability, and they're working very hard on their ballistic missile capability.

We have to save as many lives as we possibly can.

We currently have a system for taking care of sickness. We do not have a system for enhancing and promoting health.

We can do better. ...We can't ignore the inequalities that persist in our justice system that undermine our most deeply held values of fairness and equality.

One of the things I have been preaching around the world is collecting taxes in an equitable manner, especially from the elites.
