I read that interviews for a new head of the NA began in September, just after it was confirmed (after a tip from a lower level employee, I imagine) that Berger was taking docs. The resignation of the former head was "accepted" by Bush in December. I assume one of the conditions of his being allowed to resign and not, at that time, face prosecution was his cooperation in the sting that eventually got Berger. The old NA head must have been the one who gave the order from the top to let Berger do whatever he wanted in the Archives.
The former director was a Clinton political appointee, a former CO governor who had lost his reelection, and who had never done anything but be a politician. The current candidate is a non-political appointee with a long history in non-profit management.
Oh, and guess what: the Dems are holding up his confirmation. Otherwise, we'd already have a new head of the NA. Anybody surprised?
The NA's former head also had something to do with presidential libraries, too. Scary thought there.
