Three top Senate Democrats are cutting their ties with William Oldaker, a longtime Appropriations lobbyist who works as treasurer for their political action committees, according to Roll Call. The Democrats, Minority Leader Harry Reid (D-NV), Byron Dorgan (D-ND), and Ted Kennedy (D-MA), are all aiming to clean up their own houses as they push for broad ethics reforms on Capitol Hill. In the House lawmakers are following suit with Rahm Emanuel (D-IL), Denny Rehberg (R-MT), and Clay Shaw (R-FL) all releasing their PAC treasurers who are also lobbyists. Senators Barak Obama (D-IL) and Joe Lieberman (D-CT) may seek a ban on this practice.
