Former CIA Director David Petraeus told an HLN journalist he never passed classified information to Paula Broadwell and insisted his resignation last week had nothing to do with the Sept. 11 attack that killed four Americans in Benghazi, Libya.

Petraeus has been speaking with HLN’s Kyra Phillips since last week. Phillips relayed some of their conversations on the air on Thursday.

“He has insisted to me that he has never passed classified information to Paula Broadwell,” the woman he was having an extramarital affair with, Phillips said. “As long as I have known him, he has never wavered on classified information, ever. And to the best of my knowledge, you know, that has always been sacrosanct. I have also never known him to tell me something that is not true.”

Phillips said Petraeus told her he wants to testify about Benghazi — something he will do behind closed doors on Friday.

“He has said this has nothing to do with Benghazi and he wants to testify. He will testify,” Phillips said. “He has maintained to me all along this was a personal failing, Robin, which, as I said, to me was quite stunning and to many other people. He’s not the type of person that I’ve ever known to fail at anything, knowing [him] as long as I have over the years. And so he has made it very clear that this was about an extramarital affair and not over classified information or Benghazi.”
