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.

We can't rely - or no country can rely on just a single personality to carry it forward. And so what the American founding fathers understood was that institutions were built for human imperfection not human perfection.

There is nothing better than being in a classroom with really, really brilliant students, and opening up new worlds to them. That's what I love doing.
