Immigration is part of the reason why our economy is stronger and better positioned than most of our other competitors, is because we've got a younger population that's more dynamic when it comes to trade.

I can say with confidence that I never bought into the hype, and I made sure that the people around me didn't buy into the hype, and I did not surround myself with people who fed me the hype. And I'm glad of that as well.

For the sake of our children and our future, we must do more to combat climate change. Now, it's true that no single event makes a trend. But the fact is the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods-all are now more frequent and more intense.

Or we can choose to believe in the overwhelming judgment of science-and act before it's too late.

America, we weaken our ties when we allow our political dialogue to become so corrosive that people of good character aren't even willing to enter into public service; so coarse with rancor that Americans with whom we disagree are seen not just as misguided but as malevolent.

Inequality also distorts our democracy. It gives an outsized voice to the few who can afford high-priced lobbyists and unlimited campaign contributions, and runs the risk of selling out our democracy to the highest bidder. And it leaves everyone else rightly suspicious that the system in Washington is rigged against them - that our elected representatives aren't looking out for the interests of most Americans.

After all, there were thousands of so-called campus radicals, most of them white and tenured and happily tolerated. No, it remained necessary to prove which side you were on, to show your loyalty to the black masses, to strike out and name names.
