We're America, and we have to stop worrying about what happens overseas, and to be optimistic, even though nobody should think we're not going to have some difficult times.

The World Trade Center site will forever hold a special place in our city, in our hearts. But we would be untrue to the best part of ourselves and who we are as New Yorkers and Americans if we said no to a mosque in lower Manhattan.

For sure I would prefer Trump had not withdrawn from the Paris Agreement. But the fight against climate change is really done at the local level - whether it's cities, local governments or the private sector, corporate and individual. No matter what Trump says, nobody is going to go back and take the scrubber out or change back to polluting. The damage that Trump can do is if there are countries that are on the fence about whether they want to address the issue, this gives the naysayers, the doubters, those that don't want to do anything, a little more ammunition.

You can't define what's middle class, what is wealthy, what is poor.

Government by three men in a room has turned New York State into a national symbol of governmental dysfunction. Enough is enough!

The governor of Texas was a real climate change, well, "skeptic" would be a nice way of phrasing it. Still, though, Texas is a leader in renewables. So, what I care about is what politicians are actually doing, not what they are saying.

Look at all of the great strengths of America: entrepreneurialship, work ethic, natural resources, a democracy, a transparency, a willingness to be critical. Around the world, they look at us, and they say, "Why are you criticizing yourself? Why are you people arguing during the political process to elect a president or somebody else?" That's the great strength of this country.
