One by one, the indicted suspects in a case involving money laundering and illegal gambling, among them art dealer Helly Nahmad, plead not guilty in court on Friday.  Underlining the size and complexity of the case, over 30 were indicted as part of two separate but connected gambling and money laundering rings.  Mr. Nahmad is charged with helping to bankroll the operation.  “We do not believe that Mr. Nahmad has knowingly violated the law.” Said Nahmad’s lawyer, Benjamin Brafman. “We anticipate that he will be fully exonerated.”
