From the August 3 edition of MSNBC's Morning Joe:
JOE SCARBOROUGH (CO-HOST): What concerns you most about Donald Trump?
GEN. MICHAEL HAYDEN: How erratic he is, Joe. I can argue about this position or that position. I do that with the current president. But he's inconsistent, and when you're the head of a global superpower, inconsistency, unpredictability, those are dangerous things. They frighten your friends and they tempt your enemies. And so I would be very, very concerned.
HAROLD FORD JR.: General Hayden, Harold Ford, very, very quickly. Who amongst your peers that you respect greatly, whether they think like you or not think like you, that you know that's advising Mr. Trump?
HAYDEN: No one.
MIKE BARNICLE: That's a good answer.
SCARBOROUGH: I have to follow up with that, I'll be careful here. Several months ago, a foreign policy expert on the international level went to advise Donald Trump, and three times he asked about the use of nuclear weapons. Three times he asked, at one point, “If we have them, why can't we use them?”
SCARBOROUGH: That's one of the reasons why he has -- he just doesn't have foreign policy experts around him.
BARNICLE: Trump? Trump asked three times whether we can use nuclear weapons?
SCARBOROUGH: Three times in an hour briefing, “Why can't we use nuclear weapons?”
