Border Security Opposition in Big Bend National Park
Senator John Cornyn (R-Texas) has aligned himself with local leaders and Democratic state Representative James Talarico, a 2026 Senate hopeful, in opposing heightened border security measures in Big Bend National Park.
In a letter addressed to DHS Secretary Markwayne Mullin on August 7, Cornyn reflected his constituents’ view that the park’s challenging terrain serves as a “natural barrier” against significant movement. He urged Secretary Mullin to reassess proposed border security projects and suggested that discussions with local stakeholders be paused until existing concerns are adequately addressed.
Talarico expressed appreciation for Cornyn’s stance, calling it a vital step against what he described as a “corrupt Big Bend border wall.” He emphasized the importance of considering insights from local sheriffs and Border Patrol, criticizing the proposed wall as an extravagant expenditure that primarily benefits affluent contractors while failing to enhance safety for Texans.
Cornyn’s letter highlighted apprehensions voiced by a bipartisan coalition of Texas border marshals, county judges, private landowners, and advocates for Big Bend. In June, Talarico hosted a press event focused on “Common Sense Border Security” in Sanderson, Texas, as part of his “Frontera Tour,” which includes various locations along the Texas border.
At this event, Talarico was accompanied by several local and state politicians, mostly from the Democratic Party, and a number of sheriffs from border counties, including Republican Terrell County Sheriff Thaddeus Cleveland. Cleveland, who previously worked as a U.S. Border Patrol agent, has voiced his opposition to CBP projects, contending that the region’s terrain naturally deters crossings, advocating instead for the use of technology over physical barriers.
Following the June press conference, Talarico’s campaign quickly labeled Cleveland’s participation as “bipartisan” support for their border strategy, posting on social media about the backing from Republican border marshals for Talarico’s approach.
CBP recently noted that the movement of construction equipment within the park was related to repairing storm-damaged roads and conducting inspections. They clarified that while brush has been cleared in certain locations, there are no plans for a 30-foot border wall within the national park.
Plans for the Brewster County area involve creating a 17-mile vehicle barrier system, complemented by physical infrastructure and roads intended to limit vehicle access across the border. This includes the installation of steel pillars and rails designed to deter vehicles from leaving designated areas.
The initiative also encompasses the development and upkeep of roughly 325 miles of patrol roads, aiding Border Patrol agents in monitoring the more isolated locations of the region. In addition, CBP will include lighting, surveillance equipment, and underground fiber optic lines in the project.
In a media release from June, CBP acknowledged the use of legal authority under the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 to secure an environmental waiver for the project, while committing to carefully managing the area’s natural and cultural assets.
Historical data indicates that the Big Bend sector has typically encountered fewer illegal crossings compared to other regions on the Southwest border. In 2023, arrests in the area peaked at over 11,800, with more than 1,500 apprehensions occurring since October of last year.
The funding for these infrastructure projects stems from the One Big Beautiful Bill, which allocated $46.5 billion towards completing border infrastructure initiatives, including main border walls and advanced border technology.
