"These guys are bullies"
I haven't been following the Valerie Plame investigation very closely, but judging from this Time story, it seems like Patrick Fitzgerald, the special prosecutor on the case, is really getting to the Mayberry Machiavellis:
As top Bush aide Karl Rove prepares for his fourth grand-jury appearance, the federal probe into who leaked CIA operative Valerie Plame's identity to the media is believed to be wrapping up. But the investigation has taken a toll on White House aides, many of whom now fear that the special counsel, Patrick Fitzgerald, is intent on issuing indictments. "Fitzgerald's office, although very professional, has been very aggressive in pursuing people," the adviser said. "These guys are bullies, and they threaten you."
