A federal court temporarily blocked the Trump administration’s border wall construction in Texas’ Big Bend region. The decision came just weeks after the administration began erecting the first wall panels in the area.

The ruling was issued by a federal judge who found the project lacked proper environmental review. The administration had planned to build hundreds of miles of barriers along the U.S.-Mexico border. Local residents and environmental groups had opposed the project, citing concerns over wildlife and land use.

This marks the second time a court has halted Trump’s border wall plans. Earlier this year, a similar order was issued in another section of the border. The administration had argued the walls were necessary for national security. The legal challenge focused on the lack of environmental impact studies. The court’s decision is expected to delay the project until further review is completed.
