In the midst of the persecuted prosecutors case, Casino Jack keeps on rollin’: Six days after the FBI searched his home in connection with the Abramoff investigation, California Republican John Doolittle steps down from the House Appropriations Committee. “Since 2005, a Justice Department task force has been looking into payments made by Abramoff and other lobbyists to Doolittle’s wife and the spouses of other lawmakers…Doolittle also helped steer millions of dollars in military funding to one of the defense contractors tied to the bribery case of former congressman Randy “Duke” Cunningham (R-Calif.).” Update: And another, although this time not Abramoff related: Arizona Republican Rick Renzi leaves the House Intelligence Committee as the result of an ongoing investigation into a 2005 land deal. I’m sensing a pattern.
