Rep. Norm Dicks, D-Bremerton, is among seven members of the House defense appropriations subcommittee under scrutiny by ethics investigators in Congress, the Washington Post reports.

The Post obtained a document that says the investigation is examining the relationships between the members of Congress the now-closed lobbying firm, the PMA Group.

According to the Post:

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 steer federal funds to clients of the PMA Group. The lawmakers received campaign contributions from the firm and its clients. A document obtained by The Washington Post shows 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.).

The Post said the offices of Dicks and three other members of Congress did not respond to questions about the investigation.

UPDATE AT 3:10 p.m. Friday: The Associated Press has moved its own version of this story, including this quote from Dicks: "I can assure you that I have always conducted myself appropriately and in accordance with all applicable House rules and statutes. I am confident that all of my actions as a member of the House have been appropriate, and I expect that when all the inquiries are concluded, I will be completely exonerated."
