This isn't as much an R or D argument, as it is simply someone in a high public position blatantly altering or breaking the law, and both being protected by a POTUS or covering his own ***. And yes, if Holder had been appointed by a GOP President, I'd be just as hopeful to see him wearing prison orange. For me, ethics supercede party lines.
Secretary Chu has essentially employed the same tactic, but his transgressions seem to get whitewashed b/c the Solara fiasco isn't directly tied to murders of American agents.
Does anyone have any defense of Holder? And, please, keep it to the current administration. Playing the historical blame game/he did it too game can take waaaay too long.
