Jones is scheduled to make his initial appearance in federal court in Des Moines on Friday afternoon. Jones’ attorney, J. Keith Rigg, did not return a phone message.
Holtsinger was sentenced to 87 months in prison in January after pleading guilty to fraud and tax charges. Prosecutors said he took nearly $1 million that he promised to invest for acquaintances from 2009 to 2012 and used most of it to pay for living expenses and vacations.
The federal code under which Jones is charged gives judges the power to issue fines or prison terms as they see fit to anyone who disobeys their orders. The complaint says U.S. District Judge Robert Pratt and federal prosecutors had informed Jones of his secrecy obligations as a juror.
