According to Josh Marshall at Talking Points Memo, Cohens father and uncle were both doctors, but the uncle also owned a social club in Brooklyn called El Caribe that was a known Mafia hangout in the 1970s and 80s. The Russian mob, then run by a legendary godfather named Evsei Agron then by his successor, Marat Balagula, (who was suspected of killing Agron) had offices in El Caribe and pretty much ran their nefarious business out of it for some years. Saters dad, Marshall reports, was a reputed capo in the Mogilevich organized crime syndicate.
So Cohen has been associated with mobsters and con men his whole life, which probably explains the widespread assumption that he would adhere to the pledge of omertà, the mafia code of silence. That code isnt what it used to be. In 2001, Sammy The Bull Gravano finally turned on Gambino crime boss John Gotti and sent him to prison. Do you know who made the deal with Gravano? It was an assistant attorney general in the criminal division of the Department of Justice. His name was Robert Mueller.
Michael Cohen may be mobbed up, but hes no Sammy the Bull. Those who know him best seem to believe hell crack even before he has his fingers printed.
