Chicago Office
Office Overview
The Chicago Office (CHI), which is housed in the historic Rookery Building and located in the heart of the Chicago Loop, has investigated and prosecuted a wide range of international and domestic cartels, ranging from auto parts and lysine to flooring, asphalt, and collusion among sellers on Amazon Marketplace. Chicago’s lysine investigation led to the prosecution of one of the largest and most famous international cartels in history, which later became the subject of a best-selling novel and major motion picture.
