"The notorious drug trafficking kingpin Joaquín 'El Chapo' Guzmán is now imprisoned in the United States awaiting trial, following the Mexican government's decision to extradite him to the United States on January 19, 2017, the day before President Trump took office. Guzmán is charged with operating a continuing criminal enterprise and conducting drug-related crimes as the purported leader of the Mexican criminal syndicate commonly known as the Sinaloa cartel. The U.S. Drug Enforcement Administration (DEA) maintains that the Sinaloa cartel has the widest reach into U.S. cities of any transnational criminal organization. In November 2016, in its National Drug Threat Assessment, the DEA stated that Mexican drug trafficking groups are working to expand their presence, particularly in the heroin markets inside the United States. Over the years, Mexico's criminal groups have trafficked heroin, methamphetamine, cocaine, marijuana, and increasingly the powerful synthetic opioid fentanyl. Mexico's drug trafficking organizations (DTOs) have been in constant flux. [...] The 115th Congress remains concerned about security conditions inside Mexico and the illicit drug trade. The Mexican DTOs are the major wholesalers of illegal drugs in the United States and are increasingly gaining control of U.S. retail-level distribution. This report examines how the organized crime landscape has been significantly altered by fragmentation and how the organizational shape-shifting continues."
