The CIA will only hire people with impeccable credentials to be a translator. 'Impeccable credentials' means you've never lived outside the United States.

I don't have a problem with a woman being president; I just want the best candidate.

Fifty percent of the world's population lives in cities. In a couple of decades, 70 percent of the world's population will be living in cities. Cities are where the problem is. Cities are where the solution is, where creativity exists to address the challenges and where they have most impact. This is why, in 2005, the C40 was founded, an organization of cities that address climate change. It started with 18 cities; now it's 91. Cities simply are the key to saving the planet.

We've continued progress in the six months since Trump got elected, and the good thing about what we're doing is that success begets success. As we bring down greenhouse gases, for example, we've closed half of the coal-fired power plants in the country in recent years. There's more impetus to try to close the other half because you can see that it is working. So, you know, I had hoped that Trump would not do that, and it doesn't make any sense to me, but regardless, it is not as cataclysmic as it could be.

Canada sets aside 36 percent of their visas for people with skills they think their country needs. We set aside six percent. We educate the doctors, and then don't give 'em a green card.

I'd be happy to provide advice if anybody asked me no matter who the President is.

I have my own army in the NYPD, which is the seventh biggest army in the world.
