EXACTLY what this is. Take note of how this administration operates. Much different than the Clintons. This is their "answer" for the backlash from the Right Wing Terrorist paper.
The same logic is the reason that CIA papers were released. I imagine that the Attorney General found that there was no cause to prosecute the CIA agents. That announcement, by itself, would anger the Left. So the idea of a simultaneous release of the classified CIA papers was born.
Get ready for much more of this sort of "balance". When the administration does something to anger one political pole, they will throw a bone to the other side. Don't take that bone - throw it back.
