Michael Bloomberg: “I'm not running for president and I'm going to be mayor for the next 925 days.”

If we want to save lives right now, ... there is only one thing that will stop the next copycat killer, and that is, lawful armed self-defense in the schools.

There's just enough is enough. You see people who have been big gun rights advocates all of a sudden saying, well, we can't keep doing this.

The President's words matter more than anybody else. And his job, I've always thought, is to be a unifier, not to be the leader of the party, but to be a leader of this country. There are consequences to words.

I think there are enormous problems. It would be an honor if people thought I could do something about them. And I'd love to have the opportunity to try.
