I think a lot of teachers want to talk about how to continually improve performance.

When you look at what [new generation] believe in, how they value diversity, how they believe in science, how they care about the environment, how they believe in, you know, everybody getting a fair shot, how they believe in not discriminating against people for sexual orientation and you know, their belief that we have to work with other countries to create a more peaceful world and to alleviate poverty, that's the majority an entire generation that's coming up behind us.

The walls between old allies on either side of the Atlantic cannot stand. The walls between the countries with the most and those with the least cannot stand. The walls between races and tribes; natives and immigrants; Christian and Muslim and Jew cannot stand. These now are the walls we must tear down. We know they have fallen before.

I think you need to have people around you who can remind you that, actually, what you just said makes no sense. Fortunately, I have my wife to do that continually.

The Russians sought to interfere with the election process - that the cyber hacking that took place by the Russians was part of that campaign, and that they had a clear preference in terms of outcomes.

The most expensive care we can give, we're giving those Americans without insurance. It's kind of stupid that we're fighting the notion that we want to quit paying a hidden tax and be up front about covering people in a way that is cost-effective.

I hope that this [hacking] does not continue to be viewed purely through a partisan lens.I think there are Republicans as well as Democrats who are concerned about this.
