Federal prosecutors are indicting Governor Jim Doyle's biggest backer for making illegal campaign contributions.
US Attorney Steven Biskupic says businessman Dennis Troha faces one charge of fraud and one charge of making a false statement to the FBI. He faces up to 25 years in prison if convicted.
Troha has been pushing a plan to build an $808 million casino in Kenosha. But last week, he stepped aside and agreed to sell his interest in the project to the Mohegan Tribe of Connecticut.
The casino plan needs Doyle's approval.
But Troha has said his support for the Democratic governor goes beyond his business dealings.
