I've met with a group of very distinguished, experienced police chiefs a few weeks ago. They admit it's an issue. They've got a lot of concerns.

I have great respect for Senator [Bernie] Sanders's commitment to try to restore Glass-Steagall. But I do not believe that that is enough. And in fact, I don't believe it really addresses a lot of the biggest issues we have.

You just have to sort of figure out how to - getting back to that word, "balance" - how to balance the public and the private efforts that are necessary to be successful, politically, and that's not just a comment about today. That, I think, has probably been true for all of our history.

That is what I want to make clear today. A man with a long history of racial discrimination, who traffics in dark conspiracy theories drawn from the pages of supermarket tabloids and the far, dark reaches of the Internet, should never run our government or command our military.

I'm not going to be responding to [Donald Trump].

I agree with the president [Barack Obama]. I've said myself, we will not send American combat troops back to either Syria or Iraq - that is off the table.

I can't speculate on what did or did not happen. I only know what I said and what I intended to convey.
