According to Time, Rove is believed to be planning his exit from the White House. Not only Rove, but possibly an entire shake up that will oust Rumsfeld, Scott McClellan, John Snow and Andrew Card.
Sounds too good to be true
Karl Rove's colleagues don't know exactly when it will happen, but they are already laying out the reasons they will give for [his] departure...
...several of the most important lawyers who deal with special counsel Patrick Fitzgerald said they saw more clues last week that Fitzgerald is continuing to look into the possibility of charging Rove with lying to investigators or the grand jury or both.
Otherwise, [if he is not indicted] Rove is likely to wait for a chance to minimize the perception that he is being hounded out or leaving under a cloud.
...
If [Rove] leaves, he will not be alone. Several well-wired Administration officials predict that within a year, the President will have a new chief of staff and press secretary, probably a new Treasury Secretary and maybe a new Defense Secretary.
What a sorry life....
[Rove] is weary. his wife and only child, who is approaching college, miss him. He has monstrous legal bills. His unique bond with the President is under stress. His most important work is done.
