First, the union leader pleaded guilty. Then, it was his business partner’s turn. On December 14, Lawrence Ackerman, head of a pair of shell insurance brokerages, pleaded guilty in U.S. District Court for the District of New Jersey to a superseding information for health care fraud, part of a long-running scheme that fleeced a United Auto Workers benefit plan and a Blue Cross Blue Shield affiliate out of a combined $6.6 million. He had been indicted in January 2017. Sergio Acosta, former president of United Auto Workers Local 2326, pleaded guilty to his role in the scam last April. The actions follow a joint investigation by the U.S. Labor Department’s Office of Labor-Management Standards, Office of Inspector General and Employee Benefits Security Administration.
