When the question arises as to how the POTUS has abused his power, consider the plight of the AG. One could argue, "he should have known". Be that as it may, here's a guy with a rock solid reputation among DC attorneys, who now faces a lifetime reputation that's lost its glimmer. He'll bear this burden forever. I believe he thought, in error, that he was smart enough to handle his boss. He got backed into a corner before he could do anything about it. I bet he's pissed.
