Introduced: May 15, 2025
Defense & National Security
Standard Summary
Comprehensive overview in 1-2 paragraphs

The Mexico Security Assistance Accountability Act would require the U.S. Secretary of State to develop and submit a comprehensive strategy for U.S. security assistance to Mexico, with detailed plans, activities, and performance measures, and to keep Congress regularly informed. Within 180 days of enactment, the Secretary must provide an unclassified report outlining how U.S. security aid will dismantle transnational criminal networks (including fentanyl trafficking) and other crimes, boost Mexico’s military, public security institutions, and civilian-law-enforcement capacity, and strengthen the rule of law and anti-corruption efforts. The bill also requires a detailed implementation plan, a listing of participating U.S. and Mexican entities and NGOs, and clear milestones and performance metrics. It mandates ongoing bilateral reporting and annual briefings to Congress on progress, while explicitly stating that nothing in the act authorizes the use of military force against Mexico. The overall goal is to increase congressional oversight and accountability for U.S. security assistance tied to Mexico.

Key Points

  • 1Strategic planning requirement: Not later than 180 days after enactment, the Secretary of State must submit a strategy to Congress detailing how U.S. security assistance will address narcotics and related crime, bolster Mexico’s security institutions, and improve civilian rule-of-law capabilities.
  • 2Three-part strategy focus:
  • 3- Dismantle transnational criminal networks that traffic drugs (including fentanyl) and engage in related crimes such as human trafficking, weapons trafficking, cybercrime, money laundering, and precursor chemical trafficking.
  • 4- Increase capacity of Mexico’s military and public security institutions to secure borders and degrade criminal organizations.
  • 5- Strengthen civilian law enforcement, prosecutors, and courts to bolster the rule of law, address corruption, and combat impunity.
  • 6Implementation and accountability: The strategy must include a detailed implementation plan with government and NGO participants, and a detailed set of priorities, milestones, and performance measures to monitor results.
  • 7Bilateral cooperation overview: The report should cover bilateral mechanisms and engagements with Mexico (diplomatic, security assistance, technical assistance, and other cooperation).
  • 8Transparency and briefing requirements: The Secretary must provide the report in unclassified form (with an optional classified annex) and must brief the Senate Foreign Relations Committee and House Foreign Affairs Committee not later than one year after submission, and annually thereafter.
  • 9Limitations: The bill contains a rule of construction clarifying that nothing in the act authorizes the use of military force against Mexico or any entity in Mexico.

Impact Areas

Primary group/area affected: U.S. and Mexican security aid framework, including the U.S. State Department, Mexican security and judicial institutions, and the congressional committees overseeing foreign relations and security assistance. The act aims to shape future security aid programs through formalized strategy and oversight.Secondary group/area affected: Civil society organizations and non-governmental organizations involved in security, anti-corruption, human rights, and rule-of-law efforts that could participate in implementation or monitoring activities.Additional impacts: Increased transparency and accountability for U.S. security assistance to Mexico; potential changes in how programs are designed, coordinated, and evaluated due to mandated milestones and performance metrics; stronger emphasis on combating fentanyl and related criminal activity; reinforced attention to anti-corruption measures within Mexican institutions. No funding authorization is included, so any new or expanded assistance would depend on separate appropriations or authorities.
