If any Attorney General was innocent of such a charge, he would be doing EVERYTHING he could to cooperate...to find who was responsible and can them as soon as possible.
Obama's handlers are likely building a course of action to minimize his knowledge/involvement and to distance himself from his own AG.
I would guess trust between Holder, Obama and others are deteriorating fast. I imagine the big question now is, will they be willing to save the boss at their own expense?
