The investigations by two separate ethics offices include an examination of the powerful subcommittee chairman, John P. Murtha (D-Pa.), as well as others who helped the PMA Group secure earmarks for clients. The lawmakers received campaign contributions from the firm and its clients. Records obtained by The Washington Post show that the members under scrutiny also include Peter J. Visclosky (D-Ind.), James P. Moran Jr. (D-Va.), Norm Dicks (D-Wash.), Marcy Kaptur (D-Ohio) , C.W. Bill Young (R-Fla.) and Todd Tiahrt (R-Kan.)…

Under the description of the OCE inquiry, the document says investigators are looking at members who might have been “accepting contributions or other items of value from PMA’s PAC in exchange for an official act.” A Hill source cautioned that the ethics committee has not gathered a significant amount of material and has not zeroed in on specific members.

Together, the seven members have personally steered more than $200 million in earmarks to clients of the PMA Group in the last two years and received more than $6.2 million in campaign contributions from PMA and its clients in the last decade, according to an analysis by Congressional Quarterly and Taxpayers for Common Sense.
