Overview

• After announcing Proyecto Portero, the DEA described joint training that includes Mexican investigators, law enforcement, prosecutors, defense officials and U.S. intelligence personnel.
• President Claudia Sheinbaum said there is no agreement or joint operation with the DEA and stressed that legal limits on foreign agents established in recent years remain in force.
• Sheinbaum acknowledged only authorized, case‑by‑case collaboration such as police training workshops in Texas and said any foreign personnel must comply with Mexico’s National Security Law.
• DEA Administrator Terry Cole told Fox News that Mexico shows a willingness to cooperate at “record” levels and said the agency would support President Trump’s decisions on potential military actions, adding, “We will fulfill our mission.”
• Analysts link today’s friction to post‑Cienfuegos reforms curbing foreign operations, warn cooperation may shift to less transparent channels, and note the DEA’s push is driven by a U.S. overdose crisis and recent record seizures.
