President Donald Trump has not yet announced his endorsement in the Texas Senate primary runoff between incumbent Senator John Cornyn and Texas Attorney General Ken Paxton, despite stating in early March that he would be "making an Endorsement soon." The runoff election continues without the president's backing after more than two months since his initial commitment.

Trump reiterated his intention to make a decision in the race, telling reporters he will announce his choice between the two Republican candidates. The primary runoff features Cornyn, who has served in the Senate since 2002, against Paxton, the state's attorney general since 2015.

Meanwhile, Vice President JD Vance and Secretary of State Marco Rubio have been raising their public profiles within the Trump administration. Both officials have taken on more prominent roles in recent weeks, drawing attention from political observers.

The increased visibility of Vance and Rubio has generated speculation about potential successors and future presidential ambitions, though neither has announced intentions regarding the 2028 election cycle. Both men served in the Senate before joining the Trump administration and maintain significant political followings.

The Texas Senate race represents one of several key Republican primary contests where Trump's endorsement could prove influential with voters. Texas Republicans will decide between the establishment-backed Cornyn and the more conservative Paxton in their upcoming runoff election.
