A public hearing is expected in the case involving Auditor General Frank Mautino’s campaign expenses after he failed to file amended reports Monday.

The Illinois State Board of Elections is seeking amended reports to clarify hundreds of thousands of dollars in campaign expenses paid to a bank and service station in his legislative district over the course of a decade.

The deadline came and went Monday for Mautino to turn in amended campaign-expense reports as ordered by the elections board.

That means the elections board will work with all of the parties to find a date for a public hearing in which the complainant will have subpoena power.

Illinois Campaign for Political Reform Chairwoman Susan Garrett said Mautino should be granted due process, but needs to comply with the State Board of Elections’ requests.

“But there comes a point when he has to do that,” Garrett said. “He just can’t hide behind a federal investigation. We want him to be open and honest about what happened.”

Several lawmakers filed a resolution earlier this month that would remove Mautino from office.

With months-old questions from state lawmakers going unanswered, delays in the elections board case and an ongoing federal investigation, trust is hard to come by.

“Maybe at the very minimum, mistakes were made, and I think people would be forgiving, but it becomes difficult to forgive if our auditor general just will not release important requested documentation,” Garrett said.

Calls to Mautino’s attorneys seeking comment were not returned.
