Definitely worth a read!
Under Gonzales, though, almost immediately from the time of his arrival in February 2005, this changed quite noticeably. First, there was extraordinary turnover in the political ranks, including the majority of even Justice's highest-level appointees. It was reminiscent of the turnover from the second Reagan administration to the first Bush administration in 1989, only more so. Second, the atmosphere was palpably different, in ways both large and small. One need not have had to be terribly sophisticated to notice that when Deputy Attorney General Jim Comey left the department in August 2005 his departure was quite abrupt, and that his large farewell party was attended by neither Gonzales nor (as best as could be seen) anyone else on the AG's personal staff.
Third, and most significantly for present purposes, there was an almost immediate influx of young political aides beginning in the first half of 2005 (e.g., counsels to the AG, associate deputy attorneys general, deputy associate attorneys general, and deputy assistant attorneys general) whose inexperience in the processes of government was surpassed only by their evident disdain for it.
Having seen this firsthand in a range of different situations for nearly two years before I retired, I found it not at all surprising that the recent U.S. Attorney problems arose in the first place and then were so badly mishandled once they did.
