Mexico Charges Ex-Prosecutor With Treason Over Role of US Agents in Drug Raid

Mexican federal prosecutors have charged former Chihuahua state Attorney General César Jáuregui Moreno with treason, accusing him of letting U.S. agents take part in an April drug raid without proper authorization, the BBC and Al Jazeera reported. Al Jazeera called it a rare step. Jáuregui has denied the allegations.

The case brings into focus how far U.S. agents may operate on Mexican soil, a question that has been a sensitive one between the two governments.

How the case developed

• April 19: A convoy returning from an operation against suspected methamphetamine labs in a remote, mountainous part of Chihuahua veered off the road and fell into a ravine, the BBC reported. Two U.S. agents and two Mexican law enforcement officers died. Media reports have identified the Americans as CIA personnel, though Al Jazeera noted that outlets relied on anonymous sources.
• April 20: Jáuregui, then the state attorney general, said in a news release that he ruled out any involvement of foreign personnel in the state's drug operations. According to Al Jazeera, he said U.S. instructors were nearby for a drone training session and later asked to ride with the Mexican convoy back to the airport. In a news conference, the BBC reported, he described the Americans as “instructor officers” doing training work.
• Later in April: Jáuregui resigned as attorney general, Al Jazeera reported. He had served in the post from 2023.
• Last weekend: Jáuregui was arrested. At a Sunday hearing on state-level charges that include abuse of public office, he denied that he ordered or agreed to U.S. involvement, the BBC reported.
• Wednesday: Federal prosecutors announced the treason charge. A judge has ordered him held in pretrial detention while the court decides whether there is enough evidence to proceed, according to Al Jazeera. A hearing is scheduled for Saturday.

What federal officials say

Federal Attorney General Ernestina Godoy Ramos said Jáuregui allowed foreign agents to carry out activities reserved for Mexican authorities and did not share information with federal officials, the BBC reported.

Under Mexican law, the federal government must approve the activities of foreign forces on the country's soil, Al Jazeera said. The constitution requires Senate approval for the presence of foreign troops. After the crash, President Claudia Sheinbaum said the military did not know that people who were not Mexican citizens had taken part, and she called for an investigation into whether state officials had followed the constitution and the National Security Law.

Why it matters beyond one prosecutor

Al Jazeera said experts describe the treason charge as vaguely defined in Mexican law, broadly covering acts that undermine Mexico's sovereignty for the benefit of a foreign entity. It added that convictions are rare, with the last widely recognized example in 1867, when Emperor Maximilian was court-martialed and executed.

Matias Gomez Leautaud, an analyst at the consultancy Eurasia Group, told Reuters the charge appears meant to set a precedent and discourage cooperation between Mexican states and the U.S. government without federal coordination and approval, according to Al Jazeera.

The political backdrop is also part of the story. Sheinbaum has worked with Washington on crime and security but has opposed U.S. efforts to deal directly with Mexican states without federal sign-off. The BBC reported that President Donald Trump has pressed her to crack down on drug trafficking, while she has repeatedly declined offers of U.S.-led counternarcotics operations and insisted on Mexican sovereignty. Al Jazeera added that concerns have grown since Trump returned to office, noting that he has suggested the U.S. could take unilateral military action against cartels.

Jáuregui belongs to the conservative opposition National Action Party, known as PAN, while Sheinbaum leads the left-wing Morena party, both outlets noted.

What happens next

A judge must still decide whether the evidence is strong enough for the treason case to move forward, as Reuters reported through the BBC. The next court hearing is set for Saturday. Jáuregui also continues to face the state-level charges in Chihuahua.
