[Barack Obama] needs to really engage both Republicans and Democrats.

I don't accept that. I really don't care - I'm going to be like one of these deniers - I don't care what the polls say.

If we intend to provide a better life, and a better world, for future generations, we can't ignore the quality of the environment we leave them.

We have to go massively, like we did in the first Gulf War where we destroyed Saddam's ability to take Kuwait. We need to have a coalition that will stand for nothing less than the total destruction of ISIS and we have to be the leader.

For the Russians, frankly, it's time that we punched the Russians in the nose. They've gotten away with too much in this world and we need to stand up against them, not just there, but also in Eastern Europe where they threaten some of our most precious allies.

I'm not a big guy that believes that you gain energy from demonizing other people. I think you gain energy from giving people hope.

Do you think that I like to have to fight the leaders in my own party over this or that? Of course not. There's no joy in that. But John Kennedy may have said it best - sometimes my party asks too much.
