I think it was mostly Bush admin people -- they had Rove in front of the grand jury some four times.
It's a witch hunt.
There is an extraordinary amount of real, exagerrated, or fabricated leak stories being released by the MSM ahead of these indictments (or non-indictment). I believe these leaks may be intended to 1) put pressure on Fitz to indict or else look like he caved into pressure from the Bushies, and 2) create the false impression that Bush's people actually broke the law so that this case still damages Bush and the GOP if Fitz doesn't indict anyone in the Bush Administration. This looks like a major DNC propaganda campaign, and I find it interesting that crazy Howard Dean said he "wouldn't accept the prosecutor's decision" if Fitz doesn't indict anyone in the Bush Admin. This is a very strange Clintonesque case. I liked Washington politics more before the Klintoons showed up in Washington.
There's a strange story in the LA Times too about Fitz's people questioning Wilson's neighbors again TODAY about whether they knew that Plame worked for the CIA. That's strikes me as very odd--either Fitz toying with the MSM or perhaps Fitz is nervous about a weak indictment that he's filing. I hope he's just trying to confuse the MSM.
