Treasury Sanctions Sinaloa ‘El Mayo’ Network As Border Security Push Targets Mexican Lawmaker

U.S. Treasury’s OFAC designated the Sinaloa Cartel’s El Mayo faction, sanctioning five individuals and 15 companies tied to fentanyl and multi-drug trafficking. The action unusually includes a sitting Mexican federal lawmaker, Hilda Araceli Brown Figueredo, alleged to have enabled cartel protection in Rosarito, Baja California. The move coincides with Treasury’s high-level meetings in Mexico City, signaling an escalated U.S. pressure campaign aligned with broader border security and cartel enforcement efforts in 2025.
