I think that one of the greatest challenges we have today is around education. One of the things that is dividing us more and more is whether you have good prospects or you don't. Do you live a neighborhood where the schools are good? If you don't, your kids may not read until the time they're in third grade. Do you at least have access to a community college that will give you job training skills so that if you don't go for four years you will at least come out with a decent job and a decent wage. Too many people don't have that opportunity.

I don't think anybody could have predicted that they would try to use an airplane as a missile, a hijacked airplane as a missile.

Differences can be a strength.

The PDB (Bin Laden Determined to Strike in U.S.) does not say the United States is going to be attacked. It says Bin Laden would like to attack the United States. I don't think you, frankly, had to have that report to know that Bin Laden would like to attack the United States.

Every good leader is part manager and every good manager is part leader.

We have important things to talk to the Russians about, despite their meddling in our elections. I hope they're talking about a way to eventually end this horrific humanitarian crisis in Syria, end that war. The Russians have more leverage than we do. I hope they're talking about the fact that, if Kim Jong-un's long-range missiles can reach Alaska one day, they can also reach Vladivostok.

What we're hearing from everyone is that they understand that Saddam Hussein is a threat. They understand that he's been a threat for a long time.
