Sheinbaum, speaking at her morning news conference on Tuesday, rejected the DEA’s description of “Project Portero,” which the agency had unveiled as a “flagship operation” aimed at disrupting drug, firearm, and money trafficking across the U.S.-Mexico border.
“The DEA issued a statement yesterday saying there is an agreement with the Mexican government for an operation called Portero. There is no such agreement with the DEA,” Sheinbaum said. “The DEA’s statement is based on what we don’t know. We have not reached any agreement, and none of our security institutions are involved in this.”
Sheinbaum clarified that the only ongoing activity was a workshop in Texas attended by four members of Mexico’s police force.
The DEA statement had highlighted this workshop as an exercise where Mexican investigators trained at one of its intelligence centers alongside U.S. prosecutors, defense and law enforcement officials, and members of the intelligence community.
