The MSM stories have been flooding the airwaves after Petraeus resigned and it no longer makes any difference who was investigating whom, when these investigations were ongoing, etc.
He's gone from Washington, and nothing they put out there is going to have any effect on him other than to damage his reputation -- which he obviously wasn't terribly concerned about in the first place (if the MSM reports are accurate).
He wasn’t concerned about his career? Look who is leading this country - drug smoking bathhouse barry who never did a flippen thing for the USA and now hell bent on destroying it and any good American.
