Holder is part of it. An important part.
IMO, Holder should have been asked for his resignation the day that the 112th Congress was sworn in.
Given the fact that this cabal is now out in the open, Darrell Issa and co. should be dragging Holder in front of their committee *EVERY DAY* until they get answers. Every day that passes that this doesn't happen is dereliction of duty on the part of the GOP-led HoR.
