Around 15 FBI agents swarmed over Rep William Jefferson's (D-LA) Capitol Hill office this weekend conducting a search related to a public corruption investigation.
Agents already raided his homes in New Orleans and Washington on August 3, 2005.
His former aide -- Brett Pfeffer -- pleaded guilty in January to bribery charges. Businessman Vernon Jackson pleaded guilty in May to bribery charges believed related to the Jefferson probe. (WashPost)
