FARGO, N.D. — A man accused of running an illegal gambling operation in North Dakota said the case should be dismissed because the charges conflict with a plea agreement in a separate money laundering case.

Gerald Greenfield, of Bloomington, is charged in federal court with three counts, including conducting sports betting business and conspiracy to commit money laundering. Greenfield allegedly ran the gambling operation for four years and made an annual profit of between $500,000 and $600,000.

Greenfield pleaded guilty to money laundering in 2010 and was sentenced in Minnesota state court to more than four years in prison. His attorney said the plea agreement in that case can be interpreted to show that separate gambling charges would not be brought against Greenfield.

Federal prosecutors were not available for comment.
