What We Do

The mission of the OIIG is to detect, deter and prevent corruption, fraud, waste, mismanagement, unlawful political discrimination and misconduct in the operation of Cook County government with integrity, independence, professionalism and respect for both the rule of law and the people we serve. (Cook County, Ill., Ordinances 07-O-52 (2007)). The OIIG conducts investigations and issues findings and recommendations to Cook County government officials. The OIIG also investigates potential criminal violations involving the conduct of Cook County employees acting in their official capacities and refers such matters for prosecution. Because the OIIG is a fact-finding agency it cannot dictate a legal outcome.

The OIIG also serves as a liaison between the County and outside law enforcement authorities and prosecutorial agencies when cases are referred. Information is freely shared with these authorities toward the end of prosecutorial convictions.
