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.

It just seems to me that this is something that the American people deserve to see. And I have no reason to believe that [Donald Trump] is ever going to release his tax returns, because there's something he's hiding.

I'm going to have a special prosecutor. We're going to enforce the trade deals we have, and we're going to hold people accountable.

I would say that folks who have looked at this issue for a long time, whether it's Elizabeth Warren or many other economists, will tell you that right now, yes, we do need a 21st century Glass-Steagall legislation.

With all due respect, the fact is we had four dead Americans. Was it because of a protest or was it because of guys out for a walk one night who decided they'd go kill some Americans? What difference, at this point, does it make? It is our job to figure out what happened and do everything we can to prevent it from ever happening again.

I'm not going to speculate.I'm just going to run my campaign, talk about what I'm doing and why I think I'd be the best president of any of the candidates on either side.

I know that some of those plans [of the North Korea] could very well lead to a missile that might reach Hawaii, if not the West Coast. We do have to try to get the countries in the region to work with us to do everything we can to confine, and constrain them.
