According to a report by the U.S. National Drug Intelligence Center (NDIC) nicknamed Operation White Tiger, he -and now his two sons- are so involved in drug trafficking and money laundering that they "pose a significant criminal threat to the United States." While U.S. law enforcement officials have spent years investigating Carlos Hank Gonzalez and his sons Carlos Hank Rhon and Jorge Hank Rhon, the assessment by several agencies marks the first time that all three have been linked directly to the operations of major Mexican drug organizations. The report drew on information from the U.S. Drug Enforcement Administration, FBI, U.S. Customs Service, CIA, Interpol and others. The report says intelligence agencies had intercepted conversations of the Hank family coordinating drug shipments. The document concludes that the Hank family has laundered money on a massive scale, assisted drug trafficking organizations in transporting drug shipments, and is engaged in large-scale public corruption, and was closely associated with the late Juárez Cartel leader Amado Carrillo Fuentes. A report by the World Policy Institute presented to the U.S. Senate Committee on Foreign Relations, described Carlos Hank as the "primary intermediary between the multinational drug trafficking enterprises and the Mexican political system".
