The bottom line is that it's hard to find a model in which you can practically administer and sustain political support for those kinds of efforts. And what makes America complicated as well is the degree to which this is not just a black/white society, and it is becoming less so every year.

We may have different backgrounds, but we believe in the same dream that says this is a country where anything's possible. No matter who you are. No matter where you come from.

We had to get out of Chicago so quick. Election night happens, suddenly I'm talking to Ben Bernanke and Hank Paulson and trying to figure out whether the world's going to fly apart, and Michelle is trying to figure out where the girls are going to go to school. And we pack up and leave and basically our house in Chicago just became like a time capsule. My desk in my home office still had stacks of articles and bills and stuff from 2008.

I think there are a lot of factors going into an election. I think the bottom line is - is that Donald Trump is gonna be sworn in as the 45th President of the United States of America. And it's not necessarily profitable to sort of try to untangle all the different factors that went into it.

Nothing can stand in the way of the power of millions of voices calling for change.

Our intelligence communities spend a lot of time and effort gathering a lot of strands and a lot of data [on Russian hacking]. There are times where they're very cautious and they say, "We think this is what happened, but we're not certain."

It is absolutely important that we have a unified alliance and that we explain to the Russians that you cannot be a 21st-century superpower, or power, and act like a 20th-century dictatorship.
