SALT LAKE CITY (AP) — A Utah polygamist who pleaded guilty for his role in a nearly $500 million biodiesel fraud scheme says a California businessmen who helped him carry out the plan offered protection from prosecution from law enforcement. Jacob Kingston said Thursday during a trial that he and Lev Dermen had meals with law enforcement officials, including two who have since pleaded guilty to corruption charges. He says Dermen called them his “umbrella.” Dermen has pleaded not guilty to 10 counts including money laundering and mail fraud. Kingston agreed to testify against Dermen after he pleaded guilty last year to money fraud and other charges.
