I want to make sure America has got the best education system in the world. And we're retaining our workers for the jobs of tomorrow.

When what you’re doing doesn’t work for 50 years, it’s time to try something new.

I do love the Waldorf-Astoria, though. You know, I hear that from the doorstep you can see all the way to the Russian tea room.

I didn't become a Christian until many years later, when I moved to the South Side of Chicago after college. It happened not because of indoctrination or a sudden revelation, but because I spent month after month working with church folks who simply wanted to help neighbors who were down on their luck no matter what they looked like, or where they came from, or who they prayed to. It was on those streets, in those neighborhoods, that I first heard God's spirit beckon me. It was there that I felt called to a higher purpose - His purpose.

People are less certain of their national identities or their place in the world. It starts looking different and disorienting. And there is no doubt that that has produced populist movements both from the left and from the right in many countries in Europe.

This is a core principle of my presidency - if you threaten America, you will find no safe haven.
