Just about the same time we learned Scooter Libby was going to jail, this article appeared on the website of the Washington Post: 

The Justice Department is investigating whether Attorney General Alberto R. Gonzales sought to influence the testimony of a departing senior aide during a March meeting in Gonzales's office, according to correspondence released today.

In a letter to the Senate Judiciary Committee, the two officials who are leading an internal Justice Department investigation of the dismissal of nine U.S. attorneys last year said their inquiry includes the Gonzales meeting, which was revealed during testimony last month from former Gonzales aide Monica M. Goodling.

"This is to confirm that the scope of our investigation does include this matter," wrote Glenn A. Fine, the inspector general, and H. Marshall Jarrett, counsel of the Office of Professional Responsibility.

The disclosure could represent a serious legal threat to the embattled attorney general. Fine's office is empowered to refer matters for criminal prosecution if warranted.
