Why it Matters

Following his May 2026 primary loss to Texas Attorney General Ken Paxton in the GOP runoff, Sen. John Cornyn (R-TX) remains active on Texas-specific issues through the end of his Senate term in January 2027. This week, Cornyn introduced legislation to protect Texas military jobs, pushed back on border wall construction at Big Bend National Park, welcomed major economic investments in the state, and publicly posted data in support of vaccines, a notable departure from the Trump administration's recent direction on the issue.

What They're Talking About

Protecting Texas Army depots:

Cornyn introduced two pieces of legislation aimed at shielding the Corpus Christi Army Depot (CCAD) and Red River Army Depot from financial harm. The Defense Expenditure Planning for Optimizing Throughput and Sustainment (DEPOTS) Act, introduced with Rep. Michael Cloud (R-TX), would allow the Department of Defense to use budget surpluses to offset debt that depots accumulate when government-directed work is cancelled. "Army depots are a critical part of revitalizing our defense industrial base, and we must provide budgetary flexibility so they are not hampered by financial losses from cancelled government work," Cornyn said.

Separately, Cornyn and Sen. John Fetterman (D-PA) introduced the bipartisan Depot Data Transparency Act, which would update reporting requirements under the military's "50-50 rule" (a statute requiring that at least 50 percent of depot-level maintenance funds go to work performed by federal employees) to give Congress visibility into how those funds are distributed at the individual depot level. Rep. Vicente Gonzalez (D-TX) noted that CCAD's "highly trained civilian workforce has dropped by thousands due to the Army's increasing reliance on private companies for helicopter repair work."

Big Bend border wall:

Cornyn sent a letter to Department of Homeland Security Secretary Markwayne Mullin asking the agency to pause additional construction of border barriers in Big Bend National Park and Big Bend Ranch State Park until local stakeholders are consulted. "Local officials on both sides of the aisle and other stakeholders have shared with me concerns about potential impacts in areas where the terrain already acts as deterrence for illegal crossings, whether it be 1,000-foot riverbank cliffs, deep canyons, or deserts," Cornyn wrote. He said the requests from local officials "appear very reasonable to me."

Vaccinations:

Cornyn also posted vaccine mortality data on social media following a presidential executive order calling to separate the measles, mumps, and rubella (MMR) vaccine into three individual shots, saying “Since 1974, vaccination has averted 154 million deaths, including 146 million among children younger than 5 years of whom 101 million were infants younger than 1 year,” according to The Hill. It came as other Republican senators also raised concerns about the Trump administration's direction on vaccines.

In the News

Cornyn drew coverage across Texas and national outlets this week. The Austin American-Statesman and Newsmax both covered his Big Bend letter, while Mediaite framed him as a Republican senator pushing back on the Trump administration's border construction plans.

The Houston Chronicle editorial board argued that Cornyn should hope Democrat James Talarico defeats Paxton in November's general election. Meanwhile, we at Legis1 reported that Cornyn publicly warned that efforts to cancel the Senate's August recess risked "demoralizing our base of voters we're depending on in 99 days to elect Republicans." On August 11th, the Fort Worth Star-Telegram reported that 18 of 23 Texas Republican congressional members have backed Paxton for the Senate seat Cornyn currently holds.
