The Federal Bureau of Investigation was looking into alleged political corruption by former San Francisco Supervisor Harvey Milk, according to a report from Raw Story and documents revealed through a Freedom of Information Act request by activist Michael Petrelis.
None of the investigations were related to the murders. Milk and Moscone were alleged to have defrauded a community development fund, Moscone was alleged to have taken a $10,000 kickback from a McDonald's franchise, and White was accused of helping arrange a deal for someone to set up shop at Pier 39 where White owned a restaurant.
Interestingly, the files also indicate an account by a witness that White had said he would "get rid of three bastards" eight months before the murders.
The FBI determined that the unnamed witness would not be good for a court case.
After the murders, the FBI dropped its corruption investigations.
Jackson West figures this is as good a gift as any from the FBI for Harvey Milk Day.
