Seems to me that the ‘contempt’ is mutual...
If the House does not put a check on Holder, Holder will come after individual House members. Right now, Holder has 2 DOJ lawyers investigating congress over the intelligence leaks that certainly come from the WH. Holder is also trying to steal the election for zero by forcing states to drop their voter ID laws and stopping the states from purging their rolls of the dead and illegals.
The GOP must go on the attack now, or else they will be under Holder’s boot. Who knows, maybe Boner actually wants Holder to go after those pesky conservatives that want new leadership.
