MADISON, Wis. — The Citizens for Responsible Government Network didn’t want to sit on its hands and wait for a politically charged John Doe investigation that likely would never come.

So the Milwaukee grassroots political watchdog has filed a petition of enforcement with the Wisconsin Department of Justice alleging one of the area’s top law enforcement officials has violated state campaign finance laws.

The petition claims Dane County District Attorney Ismael Ozanne, a Democrat, broke several state laws during his bid this year for Wisconsin attorney general by turning in false reports, making anonymous disbursements and spending campaign cash for nonpolitical purposes.
