NSPM-4 "Military Mission for Sealing the Southern Border of the United States and Repelling Invasions"

  1. Original Date Announced

    April 11, 2025

    President Trump issued National Security Presidential Memorandum/NSPM-4 directing the Departments of Defense, Interior, Agriculture, and Homeland Security to carry out a military mission to seal the southern border of the United States and repel unlawful incursions. Citing Executive Order 14167 and the declared national emergency at the southern border, the memorandum authorizes DOD to assume jurisdiction over certain federal lands, explicitly identifying the Roosevelt Reservation but excluding Federal Indian reservations, for military operations, including construction of border barriers and surveillance systems. It grants authority to designate these areas as National Defense Areas and enables land transfers necessary for defense use. The memorandum calls for a phased implementation starting in designated sectors.
