The Politico reported this first Monday.

Thirteen senior House members — nine Republicans and four Democrats — have been served with subpoenas from defense attorneys representing Brent Wilkes, the former defense contractor charged with bribing imprisoned ex-Rep. Duke Cunningham (R-Calif.).

None of the lawmakers will comply with the subpoena, according to an official notification read on the House floor Monday evening.

Dicks is chairman of the Defense subcommittee of the Appropriations Committee.
