Trump administration asks Supreme Court to lift injunction blocking Big Bend border wall construction

The Justice Department filed an emergency request with the Supreme Court on October 21, 2026, asking the justices to lift a lower court injunction that halted border wall and infrastructure construction in the Big Bend region of West Texas. U.S. District Judge Kathleen Cardone issued the injunction on October 2, finding that Homeland Security waivers of environmental and preservation laws likely exceeded the secretary's authority because Big Bend is not an area of high illegal entry. The project spans roughly 500 miles of border and includes bollard walls, vehicle barriers, patrol roads and surveillance technology.
