Resource: DOJ Public Integrity Complaint Form
From the DOJ's website:
In August, 2003, Attorney General Lautenschlager formed the Public Integrity Unit at the Wisconsin Department of Justice. It is composed of attorneys from the Division of Legal Services and criminal investigators from the Division of Criminal Investigation. Unit team members dedicate their time to reviewing potential civil and criminal violations of our state laws that regulate the conduct of elected or appointed public officials and public employees.
Most of the cases investigated by the Public Integrity Unit are initiated at the request of a district attorney, an elected official or a law enforcement agency. The public is also invited to file complaints. View the form. More info...
