The Rev. Al Sharpton was an FBI informant who had extensive dealings with Mafia figures in New York in the 1980s and secretly recorded their conversations using a briefcase that agency technicians had modified with hidden electronic equipment, a report said Monday.
The report, on the website the Smoking Gun, said Sharpton had worked with a joint task force overseen by the FBI and the Police Department. The website posted documents that appeared to provide details of Sharpton's dealings with mob figures.
Sharpton played down his involvement with Mafia figures, although it had long been known that he worked with the FBI in the 1980s in an investigation of boxing promoter Don King.
