From ABC News:
...Stephen Bing, a wealthy film producer who, with little fanfare, has managed to steer a total of more than $16 million of his money to Democratic candidates and the supposedly independent groups that support them...
...Democratic Party officials said they knew nothing about the man who law enforcement officials tell ABC News is Bing's friend and business partner... a New York [mob] figure currently in federal prison on racketeering charges.
"[His] main activity was murder. No question about it... He was one of the top hit men in the New York area," said... a former NYPD investigator.
