Chicago has a long history of public corruption that regularly draws the attention of federal law enforcement and federal prosecutors. Chicago's political landscape has been firmly under the control of the Democratic Party for over 85 years and has been widely described as a political machine. In the 1980s, the FBI's Operation Greylord uncovered massive and systemic corruption in Chicago's judicial system. Greylord was the longest and most successful undercover operation in the history of the FBI, and resulted in 92 federal indictments, including 17 judges, 48 lawyers, eight policemen, 10 deputy sheriffs, eight court officials, and one state legislator. Nearly all were convicted on a variety of charges including bribery, kickbacks, fraud, vote buying, racketeering, and drug trafficking.
