A New York Times article (here) provides a run-down of the various current and former members of Congress under investigation for corruption by federal prosecutors.  Many of the investigations — but by no means all — are traceable to the activities of former superlobbyist Jack Abramoff, currently serving a six-year prison term who has provided information that led to the guilty plea and thirty-month sentence for former Ohio Representative Bob Ney.  There is currently one Congressman, William Jefferson, under indictment, and the FBI recently searched the residence of a California Representative whose wife worked for Abramoff.  Quite a roster of questionable dealings, to be sure.
