Karl Rove's return to the grand jury today could mean the end of the Rove investigation or the beginning of the Rove prosecution. It depends on who asked Rove to return. If Fitzgerald asked Rove to return to the grand jury, that means Fitzgerald thinks he doesn't have enough for an indictment. If Rove asked to return to the grand jury, that means Rove's lawyer, Bob Luskin, believes an indictment is imminent and is sending his client back to make a final desperate attempt to avoid indictment. Luskin did this once before when he told Fitzgerald about the Viveca Novak connection, which is certainly going to be covered in Rove's testimony today. Luskin has experienced extreme mood swings in his willingness to talk to the press about this case. If a reporter can ask him one question today, it should be who asked Rove to return to the grand jury?
P.S. For what it's worth, the buzz among the Washington press corps right now is that Rove asked to return to the grand jury.
