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.

I'd be derelict in my duty if I didn't go and continue to use every advantage that I can to promote New York's cause.

I think both of them [Donald Trump and Bernie Sanders] have [chances] because they are not the establishment, not for who they are.

On Sept. 11, 2001, thousands of first responders heroically rushed to the scene and saved tens of thousands of lives. More than 400 of those first responders did not make it out alive. In rushing into those burning buildings, not one of them asked, 'What God do you pray to?' What beliefs do you hold?'

You've got to give people a fair chance of saying what they believe, and then you've got to decide, "Do you believe 'em?"

Even though New York is the safest big city in the nation, there are still far too many illegal guns on our streets. Nearly all of them arrive from out of state - and most are sold by a small group of rogue gun dealers who refuse to obey federal laws.

Our climate is changing. And while the increase in extreme weather we have experienced in New York City and around the world may or may not be the result of it, the risk that it may be - given the devastation it is wreaking - should be enough to compel all elected leaders to take immediate action.
