AP reports that four Democratic Senators from the Judiciary Committee, including the Chair, Patrick Leahy, want a Special Prosecutor to investigate the Attorney General:

Senate Democrats called Thursday for a special counsel to investigate whether Attorney General Alberto Gonzales perjured himself regarding the firings of U.S. attorneys and administration dissent over President Bush's domestic surveillance program.

"It has become apparent that the attorney general has provided at a minimum half-truths and misleading statements," four members of the Senate Judiciary Committee wrote in a letter to Solictor (sic) General Paul Clement.
