President Claudia Sheinbaum is investigating whether U.S. authorities, specifically the FBI, were involved in the capture of drug lord Ismael "El Mayo" Zambada [1].
The inquiry touches on the sensitive nature of bilateral security cooperation and sovereignty. If the FBI operated the capture without full coordination with Mexican officials, it could strain diplomatic relations between Mexico City and Washington.
Sheinbaum said the central point of the investigation is to find out if U.S. authorities participated in the delivery of Zambada [1]. The Mexican government is seeking to determine who orchestrated the operation, and how the cartel leader was transferred [1].
Conflicting narratives have emerged regarding the operation. Reports from the Mexican investigation narrative suggest that the aircraft involved was presented as an FBI operative, which implies direct U.S. involvement [2]. This suggests a level of coordination or execution by American agents on the ground.
However, U.S. official statements have denied any participation in the capture [2]. The discrepancy between the Mexican narrative and the official U.S. position is the primary driver for the current presidential inquiry.
Sheinbaum is focusing on the logistics of the delivery to establish a clear timeline of events [1]. The investigation aims to clarify the role of foreign intelligence services in an operation that took place within Mexican territory [1].
“Sheinbaum wants to determine whether U.S. authorities, specifically the FBI, were involved in the capture of drug lord Ismael "El Mayo" Zambada.”
This investigation reflects the ongoing tension between Mexico's desire for U.S. help in dismantling cartels and its insistence on national sovereignty. If the Mexican government proves the FBI operated independently within its borders, it may lead to a public diplomatic rift or a shift in how security intelligence is shared between the two nations.
