I believe this may be the one hang-up the O Admin may have about sacking this guy. The minute they let him go it will only juice-up the witch hunt after any/all of the remaining czars. It will legitimize (in the MSM sense) more scrutiny of the whole bunch and I think they are afeared of that.
Bingo! They have to be very careful. I am predicting a round of “the new McCartyism” accusations. That should do the trick.
