If he was being blackmailed with this Broadwell affair into silence about Bengazzi, then there is now nothing further to blackmail him with. The affair is now out of the bag and he has resigned as CIA Director. So he is now free to testify truthfully about Bengazzi.
Again -- I would appreciate any input from Freepers on this who know a lot more about the legal side of this than I do, but I'm wondering ...
Does Petraeus' decision to resign have any implications for any potential future claims of executive privilege by the White House? If he is a "civilian" and no longer serving in the executive branch of the U.S. government, is he now free to testify on anything and everything without any legal pressure from the White House?
