Trump Ally Endorses Paxton Over Cornyn in High-Stakes Texas Senate Runoff

GOP Rep. Eric Burlison backs Texas Attorney General Ken Paxton in Republican primary battle against incumbent Sen. John Cornyn.

Published on Mar. 10, 2026

In a closely watched Republican U.S. Senate primary runoff in Texas, Rep. Eric Burlison, R-Mo., has endorsed Texas Attorney General Ken Paxton over incumbent Sen. John Cornyn. Burlison, a member of the House Freedom Caucus, praised Paxton as a "proven conservative fighter" who will "never back down" against the "far-left agenda." The primary race heads to a high-stakes runoff later this year, with former President Donald Trump expected to soon make an endorsement of one of the two candidates.

Why it matters

The Texas GOP Senate primary has become a proxy battle between establishment Republicans like Cornyn and more conservative, Trump-aligned figures like Paxton. The winner will face a Democratic opponent in the general election, making this runoff a crucial test of the Republican Party's direction in the Lone Star State.

The details

Paxton and Cornyn were the top finishers in the initial GOP primary, but neither won a majority, forcing them into a runoff election. Burlison, a member of the House Freedom Caucus, cited Paxton's legal battles against the Biden administration's agenda and "woke corporations" as reasons for his endorsement. Trump has indicated he plans to endorse one of the two candidates, though he has not yet made a decision.

What they’re saying

“Ken Paxton is a proven conservative fighter who will be a champion for the people of Texas in Washington. During the Biden Administration, Ken led the national legal charge to stop the Biden Border Crisis and stop the far-left agenda. He's fought for Texans' rights against woke corporations and the Austin political establishment. In the Senate, he will continue to be a fearless conservative who will never back down. That's why I'm proud to wholeheartedly endorse his campaign.”
