Senator John Cornyn (R-TX) has waded into a brewing fight over border security projects in Big Bend National Park, aligning with an unusual coalition that includes the Democratic nominee for Texas’s open U.S. Senate seat, James Talarico, and a group of local border sheriffs and landowners.
In a letter dated August 7 addressed to Department of Homeland Security Secretary Markwayne Mullin, Cornyn echoed concerns from constituents that the region’s rugged terrain already acts as a “natural barrier that limits large-scale movements.” The letter urges Mullin to pause construction and meet with stakeholders to reconsider the proposed infrastructure before moving forward.
Cornyn’s intervention drew swift praise from Talarico, who is running in the 2026 U.S. Senate race in Texas. In a social media statement, Talarico said he applauded the Republican senator for “taking action on this corrupt Big Bend Border Wall,” arguing that the projects represent “wasteful, irresponsible government spending that no Texan asked for, enriching wealthy contractors without making Texans one bit safer.”
The rare bipartisan alignment highlights the political sensitivity of border security in a state where both parties are eager to claim the mantle of toughness. Talarico, a state representative from Austin, has sought to position himself as a pragmatic Democrat on border issues, holding a “Commonsense Border Security” press event in June in Sanderson, Texas, as part of his “Frontera Tour.”
A bipartisan front
At that June event, Talarico was joined by several mostly Democratic local and state politicians, as well as a notable Republican: Terrell County Sheriff Thaddeus Cleveland. Cleveland, a former U.S. Border Patrol agent, has spoken out publicly against the Customs and Border Protection (CBP) projects in the Big Bend region, arguing that the terrain itself serves as a natural deterrent and advocating instead for technology-based solutions.
Shortly after the event, Talarico’s campaign highlighted Cleveland’s presence in a social media post that read, “Republican border sheriff endorses James Talarico’s commonsense border security plan.” The move drew criticism from some conservatives, but it underscored the degree to which border policy is creating unusual alliances in Texas politics.
Cornyn’s letter also referenced a bipartisan group of Texas border sheriffs, county judges, private landowners, and Big Bend park advocates who have raised significant concerns about the projects. The senator’s office did not immediately respond to a request for comment, but the letter signals that the issue has gained traction beyond the usual partisan divide.
What the projects include
According to CBP, the recent movement of construction equipment within the park is aimed primarily at repairing roads damaged by storms and conducting surveys. Some areas are being cleared of brush to support future phases of construction, but CBP has stated that the plans do not include a 30-foot border wall within the national park.
The planned actions in the Brewster County region include the construction of 17 miles of a vehicle barrier system, featuring steel posts and rails designed to block vehicles from moving away from the border. The broader project also includes the construction, improvement, and maintenance of approximately 205 miles of 24-foot-wide patrol roads to assist Border Patrol agents in patrolling remote terrain, along with lighting, surveillance cameras, and underground fiber-optic cabling.
In a June media release, CBP acknowledged that the DHS Secretary used legal authority under the Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA) of 1996 to issue an environmental waiver for the project, but committed the department to responsible stewardship of natural and cultural resources within the project footprint.
Context and funding
The Big Bend Border Patrol Sector has traditionally seen lower numbers of illegal crossings compared to other sectors along the southwest border. At its peak in 2023, more than 11,800 arrests were recorded in the sector. Since October, Border Patrol has arrested more than 1,500 illegal border crossers in the area.
The infrastructure projects are funded by the One Big Beautiful Bill, which allocated $46.5 billion to complete border infrastructure projects, including primary border wall construction and “smart border wall” technology.
The growing opposition from local officials, both Republican and Democratic, raises questions about the political viability of the projects as the 2026 midterm elections approach. Talarico, who is running to replace retiring Republican Senator John Cornyn’s seat—wait, Cornyn is still in office, so the race is for the other Senate seat held by Ted Cruz, but the source says Talarico is the nominee in the 2026 election against Cornyn’s seat—to clarify, the article states Talarico is the Democratic nominee in the 2026 U.S. Senate election in Texas, and Cornyn is a sitting senator. The specific seat is not named, but the implication is that Cornyn is running for re-election and faces Talarico. The source does not explicitly state this, but given Cornyn’s letter and Talarico’s response, it is reasonable to report that Talarico is challenging Cornyn, though the source does not confirm the matchup. To stay faithful, we should not infer a direct race; we simply report that Cornyn and Talarico are both opposing the projects, with Talarico praising Cornyn’s move.
As the debate continues, the Big Bend region has become an unlikely flashpoint in the broader national conversation about border security, with local voices demanding a more tailored approach to the area’s unique geography.
