The Senate Judiciary Committee, which is heading an investigation into the recent quick and dirty cleansing of 8 -- and maybe 9 -- U.S. Attorneys, will vote today on whether to subpoena five DOJ officials if they fail to appear. Those officials include the chiefs of staff for both U.S. Attornery General Alberto Gonzales and Deputy Attorney General Paul McNulty (Kyle Sampson and Mike Elston, respectively), acting Associate Attorney General William Mercer, Director of the Executive Office of the United States Attorney Michael Battle (who has just resigned), and the Justice Department's White House liaison, Monica Goodling. During a marathon of hearings before the House and Senate this past Tuesday, the testimony by six of the U.S. Attorneys incriminated these officials. TPMmuckraker has a good rundown on their alleged involvement in the firings. For Mojo coverage of the senate hearing on Tuesday and further developments, click here, here and here.
