Key Takeaways 

  • The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) designated six individuals and entities tied to Cartel del Noreste (CDN)—one of Mexico’s most violent drug trafficking organizations—including two CDN-affiliated casinos used for money laundering and drug operations near the U.S.-Mexico border. 
  • OFAC’s actions are the latest examples of a broader national security strategy to use sanctions, AML authorities, criminal prosecutions, and other tools to counter cartels on the U.S.-Mexico border. These efforts have targeted in particular non-traditional financial institutions such as casinos, public-facing professionals, and disinformation actors. 
  • The State Department designated CDN as a foreign terrorist organization (FTO) on February 20, 2026, and today’s designations were issued under both Executive Order 14059 (narcotics trafficking) and Executive Order 13224 (terrorism), underscoring the U.S. government’s treatment of major cartels as hybrid criminal-terrorist threats.
