Sinaloa Governor and Culiacán Mayor Step Down After U.S. Drug Trafficking Indictment

The governor of Mexico's Sinaloa state and the mayor of its capital city said Saturday that they would temporarily step down from office, two days after a federal grand jury in New York unsealed a sweeping five-count indictment alleging that they and eight other Mexican officials helped a faction of the Sinaloa cartel move "large quantities of narcotics" into the United States in exchange for political support and bribes.

Gov. Rubén Rocha Moya, 76, a senior figure in President Claudia Sheinbaum's ruling Morena party, has held the Sinaloa governorship since 2021. The indictment alleges he met with the so-called "Chapitos" — the sons of jailed cartel leader Joaquín "El Chapo" Guzmán Loera — before his 2021 election and assured them that, if elected, he would install officials "friendly" to their drug-trafficking operations across state government. He is named alongside the mayor of Culiacán, Juan de Dios Gámez Mendívil, also a Morena member, and eight current and former federal, state and municipal security officials. Both elected officials denied the charges in statements published Saturday and said they would temporarily relinquish their positions to clear their names.

The indictment, unsealed Wednesday by the U.S. Drug Enforcement Administration and the U.S. Attorney's Office for the Eastern District of New York, marks one of the most aggressive American legal moves ever taken against sitting Mexican officials. Acting U.S. Attorney Joseph Nocella said in a statement that the defendants had "converted the institutions of the Mexican state into instruments of the cartel." The case is part of a broader DEA push, accelerated under the Trump administration, that has classified the Sinaloa cartel and four other Mexican criminal organizations as Foreign Terrorist Organizations and has authorized prosecutors to pursue narco-terrorism enhancements that carry sharply higher penalties.

The political fallout in Mexico is likely to be severe. President Sheinbaum, who took office in October 2024 and has tried to maintain a cooperative-but-firm posture with the Trump administration, on Saturday acknowledged the gravity of the charges but defended the rule-of-law process within Mexico, saying her government would "not interfere" in either the U.S. case or any parallel Mexican investigation. Opposition parties have demanded the immediate expulsion of the indicted officials from Morena and called for an emergency session of the Mexican Senate. Sinaloa, a coastal state with a population of about 3 million, is the historical heartland of the cartel that has dominated U.S.-bound fentanyl, methamphetamine and cocaine flows for two decades.

The indictment lands at a fraught moment in U.S.-Mexico relations. The Trump administration has spent the past year escalating both rhetorical and policy pressure on Mexico over migration, fentanyl and tariffs, including a threatened 25% across-the-board tariff and a recent series of unilateral U.S. military strikes on cartel-linked targets in maritime waters off the Mexican coast. Sheinbaum has publicly opposed any uninvited U.S. military activity inside Mexican sovereign territory. Whether the Sinaloa indictment is viewed in Mexico as a legitimate law-enforcement action or as another front in Washington's pressure campaign will shape how aggressively Sheinbaum's government cooperates with the U.S. case in the months ahead.
