You don't insult American Muslims and religiously profile them the way that has been suggested by Ted Cruz.

I know that some of those plans [of the North Korea] could very well lead to a missile that might reach Hawaii, if not the West Coast. We do have to try to get the countries in the region to work with us to do everything we can to confine, and constrain them.

If you help create the profits, you should be able to share in them, not just the executives at the top.

I don't think the police, even if we train them, can be, you know, as good as psychologists and psychiatrists and others knowing what is happening to somebody. So we've got to have a more coherent, comprehensive approach.

If I had lost the popular vote but won the electoral college and in my first day as president the intelligence community came to me and said, "The Russians influenced the election," I would've never stood for it. Even though it might've advantaged me, I would've said, "We've got to get to the bottom of this." I would've set up an independent commission with subpoena power and everything else.

Being human, we are imperfect. That's why we need each other. To catch each other when we falter. To encourage each other when we lose heart. Some may lead; others may follow; but none of us can go it alone.

I don't think any of us have the answers to everything. There's no human being on earth who fits that category. So why wouldn't you ask for help? Why wouldn't you run ideas by people that you respect? Too many young people cast around trying to figure out what the answer is themselves, because they're afraid to come back and say, "I'm not sure I understood you," or "Could you give me a little more information about what you need?" Just do that. It saves you time, it saves your boss's or mentor's time. And it's a great lesson to learn.
