Vacation time?

Interesting little blurb at the Corner today about the Plame investigation:

one thing we haven't been hearing much about in the last few weeks is the Patrick Fitzgerald CIA leak investigation. Neither, apparently, have some of those who have been most affected by it. Sources close to Karl Rove say they have not heard from Fitzgerald since December, when there was public speculation that Fitzgerald was going to make a decision on Rove's future fairly soon. So far, however, there's been nothing, and while reporters have been keeping an eye on the courthouse in Washington, there apparently haven't been any Fitzgerald sightings there recently.

Wither Patrick Fitzgerald and his all-seeing, all-knowing powers of investigation?
