So, did Rover get a target letter saying he's about to be charged?

According to Jason Leopold he did. That means that Special Prosecutor Patrick Fitzgerald is now aiming the investigation into the Plame leak case at Karl Rove and possible charges of perjury and lying to investigators.

Despite vehement denials by his attorney, who said this week that Karl Rove is neither a "target" nor in danger of being indicted in the CIA leak case, the special counsel leading the investigation has already written up charges against Rove, and a grand jury is expected to vote on whether to indict the Deputy White House Chief of Staff sometime next week, sources knowledgeable about the probe said Friday afternoon.

Special Prosecutor Patrick Fitzgerald was in Chicago Friday and did not meet with the grand jury.

Rove's attorney, Robert Luskin, was informed via a target letter that Fitzgerald is prepared to charge Rove for perjury and lying to investigators during Rove’s appearances before the grand jury in 2004 and in interviews with investigators in 2003 when he was asked how and when he discovered that Valerie Plame Wilson worked for the CIA, and whether he shared that information with the media.

We could say, it's about time, but that would be unfair.

Patrick Fitzgerald is still the federal prosecutor in Chicago and has to keep that office running. Among other things, he has to provide oversight into this case.

Moving too quickly, of course, would be a mistake for several reasons. First is to make sure all ducks are in a row, but being too speedy would be something of a mistake. If Rove is guilty of any offence, it would be nice if he was out of the brackets for a Presidential pardon.
