On Friday, President Donald Trump directed the transformation of a 60-foot-wide federal strip along the US-Mexico border into a military installation. Known as the Roosevelt Reservation, this land spans California, Arizona, and New Mexico. Consequently, the Department of Defense now controls it, taking over from other agencies.
The White House memorandum allows troops to detain migrants for trespassing until the Border Patrol arrives. However, a U.S. military official told The New York Times that soldiers lack authority for immigration arrests and can only temporarily hold individuals. For this reason, state National Guard units will also operate in the zone.

The move sparks legal debate. Federal law limits active-duty troops in domestic law enforcement. Therefore, analysts question the plan’s boundaries. “This creates a pathway for quasi-military detention,” said Adam Isacson of the Washington Office on Latin America, per The New York Times.

Details remain unclear. For instance, officials are still deciding how long troops can hold migrants. They also plan the area’s signage, languages, and warning protocols. Neither the White House nor the Defense Department shared specifics on implementation.
The directive, reported earlier by The Washington Post, formalizes weeks of planning. It aligns with Trump’s tough border security stance and responds to ongoing migration challenges. Yet critics argue it pushes military involvement too far, risking legal overreach.
