President Donald Trump has publicly endorsed Texas Attorney General Ken Paxton in the upcoming GOP Senate primary runoff [1].

The endorsement arrives as Trump seeks to consolidate his control over the Republican party by removing candidates he views as insufficiently loyal [3]. By backing Paxton against Senator John Cornyn, Trump is attempting to demonstrate his ability to shift the outcome of key midterm contests [1].

The runoff is scheduled for later this month in May 2026 [2]. This intervention follows a pattern of the president using his platform to influence primary battles across the U.S. to ensure a loyalist base in Congress [3].

Paxton, the state's Attorney General, now enters the final stretch of the primary with the formal support of the party's most influential figure [1]. This move places him in direct opposition to Senator Cornyn, who has faced challenges from the right wing of the party [1].

Trump has repeatedly touted his influence over the 2026 midterm primary contests [1]. He said his goal is to ensure that the candidates who emerge from these primaries align with his specific political agenda [3].

The Texas runoff is seen as a critical bellwether for the broader midterm elections. The result will indicate whether Trump's endorsement continues to act as a decisive factor in Republican nominations [3].

This endorsement signals a strategic effort by Donald Trump to purge the GOP of moderates and establish a legislative wing composed entirely of loyalists. By intervening in a high-profile Texas Senate race, Trump is testing the strength of his electoral mandate within the party ahead of the broader 2026 midterm cycle.
