Rep. Jerry Lewis (R-CA) [1] has become involved in a larger investigation, stemming from Randy "Duke" Cunningham's bribery scandal, into whether lawmakers may have been payed by lobbyists and contractors in exchange for lucrative federal earmarks.  

Last week the FBI subpoenaed records [2] from San Bernandino County and the city of Redlands connected with a lobbying firm both entities have done business with, Copeland, Lowery, Jacquez, Denton, & White and Rep. Lewis. The firm employs several people with ties to Lewis and clients of the firm have given heavily to Lewis and received milions in "earmarks" from the government.  

Several employees of the firm are particular focuses of the investigation, among them former California Rep. Bill Lowery, who employed Rep. Lewis's Appropriations Committee deputy staff director, Jeff Shockey, after he left Lewis's office (he later returned).

Also a focus of the investigation is Letitia White, a former Appropriations Committee staffer to Rep. Lewis known for her skill at shoehorning money for Lewis's projects into big spending bills. She became "K Street's queen of earmarks" when she left the congressman's office for the private sector for her ability to influence earmarking legislation for the benefit of her lobbying clients. The New York Times profiles [3]her career with Lewis, and her lucrative lobbying career after in the context of the investigation.
