Every day that Attorney General Alberto Gonzales is allowed to remain in office is corrosive to constitutional governance and an invitation to further politicization of the Justice Department.

That is the main lesson of former Deputy Attorney General James Comey’s astonishing revelations on May 15 about Gonzales’s sinister involvement in a March 2004 effort to continue a then-secret warrantless eavesdropping program after it had been declared unlawful by then-Attorney General John Ashcroft and his subordinates.

Meanwhile, the May 14 resignation of Paul McNulty, Comey’s successor as deputy attorney general, further depleted the ranks of principled professionals in the demoralized department, which Gonzales has been filling with inexperienced political hacks. In the words of Arlen Specter, the Senate Judiciary Committee’s senior Republican, as long as Gonzales is in charge, “it’s embarrassing for a professional to work for the Department of Justice.”

Comey, testifying to the Senate Judiciary Committee, described an extraordinary scene the night of March 10, 2004, in George Washington University Hospital’s intensive care unit. Ashcroft, so sick with pancreatitis that he had designated Comey as acting attorney general, was drugged with painkillers after the removal of his gallbladder the day before.
