MARFA, Texas -- Landowners, ranchers and business owners in the Big Bend region of Texas along with a nonprofit organization dedicated to protecting the region's landscape and heritage are suing to stop the Trump administration's plans to build a wall and other border infrastructure through the remote section of the state.

The lawsuit, filed by Conserve Big Bend and six landowners and with the support of dozens more people along the border, comes as the administration is ramping up a $46 billion effort to line the roughly 2,000-mile southern border with a collection of 30-foot (9-meter) steel bollard walls, vehicle barriers, and technology intended to keep out smugglers and migrants.
