U.S. Ambassador to Mexico Pushes Back on Sheinbaum Sovereignty Warning, Says Turning Cartel Fight Into Politics Is 'a Missed Opportunity'

U.S. Ambassador to Mexico Ronald Johnson said Monday that the fight against drug cartels "should unite us, not divide us," after Mexican President Claudia Sheinbaum accused sectors in the United States on Monday of interfering in Mexico's internal affairs over recent drug trafficking and extradition cases.

"The fight against cartels should unite us, not divide us," Johnson wrote on X. "Every moment spent turning this shared security challenge into a political dispute is a missed opportunity to strengthen our partnership and protect the people we serve."

Johnson's comments came a day after Sheinbaum delivered a speech in Mexico City criticizing U.S. pressure surrounding organized crime investigations involving Mexican officials. Speaking before thousands gathered at the Monument to the Revolution, Sheinbaum said Mexico "does not accept interference" and questioned whether Washington's actions reflected a "genuine" interest in helping combat organized crime.

"When from abroad they dictate who is guilty and who is not, when they seek to pressure our institutions from outside, we are no longer talking about cooperation, we are talking about interference," Sheinbaum said.

The dispute centers on charges announced in April by U.S. prosecutors in New York against Sinaloa Gov. Rubén Rocha Moya and nine other current and former Mexican officials accused of collaborating with the Sinaloa Cartel. U.S. authorities alleged the officials helped facilitate shipments of fentanyl, heroin, cocaine and methamphetamine into the United States.

Rocha Moya, a member of the ruling Morena party, has denied the accusations, calling them baseless. Mexico's Attorney General's Office has said the extradition requests cannot proceed unless the United States provides sufficient evidence under Mexican law.

Sheinbaum suggested Sunday that the investigations could be politically motivated ahead of U.S. midterm elections in 2026 and Mexico's federal elections in 2027. "Mexico is nobody's piñata," she said.

The Mexican president also linked recent tensions to the April 19 deaths of two U.S. agents in the northern state of Chihuahua following an operation against a clandestine synthetic drug laboratory. Mexican authorities said the agents had no official accreditation to operate in the country.

Despite the dispute, Sheinbaum said Monday that communication with the Trump administration remains active across diplomatic, security and defense channels. She also said she did not believe President Donald Trump himself was directing what she described as an "offensive" against Mexico, instead blaming far-right sectors in both countries for escalating tensions.
