One thing I have penned down. The first person to mention the film, was Petraeus, when he first testified. From that point on, the president and Hillary and UN Rice were stuck on the film.
Trying to predict from here what will happen is useless. The congressmen in House and Senate will hold their hearings and they know what to do with Petraeus as they know the law regarding testifying and will follow that to get Petraeus testimony.
I have to believe that Petraeus is an honorable man who will tell the truth no matter what that means to him or the president or Hillary or Rice or anyone else involved.
Until his testimony is released to the public, I have no opinion what happened in Benghazi to cause the death of our men as I think his testimony is the beginning of the truth that will unlock the rest.
General P will not say ANYTHING.
