Donald Trump used undocumented labor to build the Trump Tower. He underpaid undocumented workers, and when they complained, he basically said what a lot of employers do: "You complain, I'll get you deported."

The challenge is to practice politics as the art of making what appears to be impossible, possible.

I hope Donald Trump will be a successful president.

Increasingly, we are seeing cyber attacks coming from states, organs of states. The most recent and troubling of these has been Russia.

I keep telling people I want to close the deficit, and one of the deficits is want to close is the fun deficit.

The middle class is both real and aspirational. And I want to make sure that it remains strong and it gives people a sense of security and confidence and optimism about their futures.

Donald Trump can't even handle the rough and tumble of a presidential campaign. He loses his cool at the slightest provocation. When he has gotten a tough question from a reporter, when he is challenged in a debate. When he sees a protester at a rally. Imagine, if you dare imagine, imagine him in the Oval Office facing a real crisis. A man you can bait with a tweet is not a man we can trust with nuclear weapons. And in the end, it comes down to what Donald Trump doesn't get, America is great because America is good.
