• President Trump says he will make a Texas Senate endorsement today, calling for the non-endorsed candidate to drop out.
  • The move targets the runoff between Sen. John Cornyn and Attorney General Ken Paxton, as GOP leaders seek to avoid a costly intraparty fight.
  • Trump's decision could reshape donor flows and media narratives ahead of the general election.

President Donald Trump announced he will issue an endorsement in the Texas Republican Senate primary later today, urging the candidate he does not back to "immediately DROP OUT" in order to unify the party. The statement, posted on his social media platform, frames the endorsement as a way to avoid a prolonged and divisive runoff that could drain resources ahead of the general election.

The announcement comes as the race between incumbent Sen. John Cornyn and Texas Attorney General Ken Paxton heads to a May runoff after neither secured a majority in the March primary. Republican leaders have grown increasingly concerned that a bitter, expensive contest could weaken the party's chances in what is otherwise a safe seat, forcing the national and state campaign apparatus to reallocate funds toward an intraparty battle.

"President Trump recognizes the need to consolidate support and avoid a fratricidal fight," a person familiar with the matter said. "An early endorsement could reduce spending and help the party focus on flipping other seats."

Sources close to both campaigns indicate that Trump has not yet tipped his hand, and the timing of the announcement has left operatives scrambling. Some GOP insiders hope Trump will back Cornyn, who has strong ties to establishment donors and has been a reliable vote for the president's agenda. Others note Paxton's vocal support for Trump's election fraud claims and his alliance with the president's allies in the House. A refusal to endorse or a delay could prolong the uncertainty.

Trump's public posture—teasing endorsements and calling for losers to drop out—signals his continued dominance over Republican primaries. It also raises the stakes for the candidates: a Trump endorsement could quickly reshape donor flows and media narratives, while the absence of one could force both campaigns to spend heavily through the spring.

The Texas runoff is the latest in a series of costly intraparty contests that have frustrated party leaders. In previous cycles, Trump's backing has often proved decisive, with trailing candidates frequently exiting the race. However, when he has remained neutral, primaries have sometimes dragged on, draining resources that could be used to challenge Democrats in more competitive states.

Now attention turns to Trump's formal endorsement. His call for the non-endorsed candidate to drop out is explicit, but it remains unclear whether that candidate will comply. Paxton has shown no signs of stepping aside, and Cornyn has insisted he will run a full campaign.

Attempts to reach the Trump campaign for additional comment were not immediately successful.
