MARTHA RADDATZ (HOST): In his fiercely worded op-ed in The New York Times, former CIA Acting Director Michael Morell blasted Trump as unprepared and dangerous and endorsed Hillary Clinton. Michael Morell joins us now. Mr. Morell, I want to first get your reaction to what Rudolph Giuliani said.

MICHAEL MORELL: One thing that struck me right off the bat was what he said about Benghazi. There is this view out there that she lied about what caused the attack. That she said it was the video. I think one of the really interesting things that is in early 2014, the Federal Bureau of Investigation walked into the House Permanent Select Committee on Intelligence, and they said that we believe the video was a motivation in this attack. Abu Khattala, who is the only person arrested, said that the video was a motivation. So this idea that the video played no role, which Republicans keep repeating over and over and over again, just isn't true.

RADDATZ: But those parents have said she said those things to them. That has resonated among the voters.

MORRELL: She said it was terrorism, right? To Chelsea [Clinton]. She said to them it was the video. Those two things can both be true at the same time. And it turns out, right, it turns out that the video did play a role in that attack and Republicans don't want people to believe that.
