NLS has the stories here and here. And remember, all jobs in the Virginia Attorney General's office are at the pleasure of the Attorney General (the "career" job line from McDonnell is because they keep on some of the guys because they are GOP hacks), so it's not going to be so easy for "Taliban Bob" to say he wasn't responsible for this. I mean, either he KNEW what was going on and did nothing, which is bad, OR he did NOT know what was going on in his own office, which is also bad. Either way, Bob McDonnell has proven that he should not be the next Governor of Virginia.
P.S. Echoes of Jerry Kilgore: "It would be both amazing and pathetic if the Attorney-freaking-General was the only guy that didn’t know about illegal activity in his own office."
P.P.S. Also see here for the classic exchange when then-LG Tim Kaine said to Jerry Kilgore in a debate, "Unless these [press] reports are completely wrong, your office did something that was wrong." Sounding hysterical, Jerry Kilgore responded (in what became a source of never-ending ridicule on the blogs): "I have no duty to you Mister Lieutenant Governor." LOL.
