The Trump administration is asking the Supreme Court to let it resume building a border wall through Texas's Big Bend region. A lower court had halted construction, a setback to one of President Donald Trump’s key projects. The administration has been pushing forward with the wall from the Pacific Ocean to the Gulf of Mexico. Ranchers, residents and environmentalists in Big Bend oppose the project, citing low illegal immigration in the area. Judge Kathleen Cardone ordered a stop to construction on Oct. 2, siding with opponents who argue the waivers used to bypass regulations exceed the secretary of Homeland Security's authority.
