In court documents filed on Tuesday, Curtis Briggs, an attorney for Raymond "Shrimp Boy" Chow, says the FBI alleged that San Fransisco's Mayor Ed Lee took bribes in exchange for favors. Chow was arrested as part of the investigation into CA state Senator Leeland Yee, who has plead guilty to corruption chargers. Chow's Lawyer, Curtis Briggs, is seeking to dismiss the indictment against Chow on the grounds that the government is selectively prosecuting him while while turning a blind eye to Ed Lee and other SF politicians who have been caught up the investigation.
