Mexico charges former Chihuahua prosecutor with treason over alleged US role in drug raid

Mexico has charged former Chihuahua Attorney General Cesar Jauregui with treason over allegations that he allowed United States agents to take part in an antidrug operation on Mexican territory. The case centres on an April raid in the northwestern border state and has revived debate over how far foreign law enforcement can operate in Mexico. It also highlights the sensitivity of security cooperation between Mexico and the United States, particularly when it involves state-level authorities.

According to the supplied material, the charge was announced on Wednesday and relates to an operation in which two US agents and two Mexican law enforcement officials later died in a car accident on 19 April. Questions emerged after reports, citing anonymous sources, said the US agents had been working with state police in the destruction of a drug laboratory. Under Mexican law, the federal government must approve the activities of foreign forces on Mexican soil, and the case has raised doubts about whether that requirement was followed.

President Claudia Sheinbaum has said her government was not aware that US agents had been involved in the Chihuahua operation. She said at the time that the military did not know there were people taking part who were not Mexican citizens, and she called for an investigation into whether state officials had respected the constitution and the National Security Law. Those rules govern the presence and activity of foreign forces in Mexico, and the constitution requires Senate approval for any foreign troops in the country.

The treason charge is significant because it touches on sovereignty, federal authority and the limits of cross-border security cooperation. Mexico has worked with the United States on crime and insecurity, but the current administration has opposed any direct US engagement with Mexican states without prior federal authorisation. The case therefore goes beyond one operation in Chihuahua and raises the possibility of a legal precedent for future cooperation between state authorities and foreign agents.

The dispute also sits within a longer history of Mexican concern over US intervention. The supplied material notes that Mexico has a long record of tension over foreign involvement, including multiple military invasions that continued into the early 20th century. That history helps explain why even limited participation by foreign agents in a domestic security operation can become politically and legally sensitive.

It also shows why federal approval procedures are treated as central to Mexico's sovereignty framework. What remains unclear is the full chain of authorisation for the April operation and whether any federal body approved the presence of the US agents. It is also not clear what evidence prosecutors will rely on to support the treason allegation against Jauregui.

The case is likely to be watched closely for its impact on bilateral security cooperation, state-federal relations in Mexico and the handling of foreign participation in future anti-drug operations.
