Now to general petraeus' very public mea culpa. The former head of the cia making his first public speech since his resignation speaking at an rotc dinner last night. Abc's david kerley has the latest. Good morning, david. Reporter: David petraeus has been basically radio silent in the nearly five months since his ses rig nation. In a piece in a newspaper this morning, the image repair campaign has been launched. It is a david petraeus we haven't seen before. I join you keenly aware that I am regarded in a different light now than I was a year ago. Reporter: Remorseful for the affair with his biographer that led to his resignation as cia director. How deeply I regret and apologize for the circumstances that led to my resignation from the cia and caused such pain for my family, friends and supporters. Reporter: This is a veterans group in los angeles which clearly supported petraeus he took the stage as he tries to rebuild his reputation. It was a spectacular fall from grace. The four-star general would took command in iraq and managed a surge of troops which led to their event withdrawal then afghanistan as the top general. It was during his time there that he met paula broadwell a former army officer writing book on the general. That relationship later became an abare exposed through e-mails after a tampa woman complained of threatening e-mails. The investigation led back to petraeus who was then running cia. We have heard nothing from broadwell or from the former general who was still protected by a security detail until now. Petraeus hoping to repair his image as well as relationships still scarred by his actions. I know that I can never fully assuage the pain that i inflicted on those closest to me and on a number of others. Reporter: It is clear that petraeus wants a future role of some kind perhaps with veterans, that is what he is writing about this morning in a newspaper article. Petraeus will have to win over, though, a lot of hearts disappointed by his actions a couple of years ago. Robin. Well received last night as we saw. All right there, david, thank you.
