Cornyn pulls in millions after narrow primary win, but FEC inquiry clouds Texas Senate campaign momentum

Texas – A high-stakes Texas Senate runoff is growing more intense, with money surging in and new scrutiny emerging at the same time.

U.S. Sen. John Cornyn entered 2026 facing one of the toughest political fights of his long career, challenged by Texas Attorney General Ken Paxton and U.S. Rep. Wesley Hunt in a heated Republican primary. Despite expectations that Paxton would dominate, Cornyn narrowly edged out his rival by just one percentage point in the March 3 primary, setting up a runoff election scheduled for May 26.

In the months leading up to and immediately following that razor-thin victory, Cornyn’s campaign saw a sharp rise in financial support. According to campaign figures released Tuesday, he raised nearly $9 million in the first three months of the year—almost $2 million more than what he brought in during the final quarter of 2025.

Even more striking, $3.4 million of that total came in the four weeks after the primary, signaling a surge of momentum as the runoff battle began to take shape. By March 31, the campaign reported more than $8 million in cash on hand, giving Cornyn a strong financial position heading into what is expected to be an expensive and closely watched race.

Cornyn’s campaign manager, Andy Hemming, praised the numbers, calling it a “massive fundraising haul.” He also used the moment to draw a sharp contrast with Paxton, stating, “Sen. Cornyn is our strongest nominee, he is one of President Trump’s most effective legislative partners, and our voters will fully understand the choice in this runoff election over the next seven week,” and warning, “A disastrous nominee like Ken Paxton risks our strong Texas House majority and numerous congressional seats.”

Fundraising surge meets new scrutiny

While Cornyn’s financial strength appears to be growing, a separate issue has emerged that could complicate his campaign’s trajectory. A political action committee tied to his campaign, the Cornyn Lonestar Victory Fund, is now facing questions from the Federal Election Commission.

The FEC recently sent a letter to the committee asking why it failed to disclose “one or more” contributions from the Energy Transfer Employee Management Company PAC in its fourth-quarter filing. The inquiry focuses on a $5,000 donation that was not properly reflected in the report.

Salvatore Purpura, the fund’s treasurer, responded quickly, confirming that the donation had been received and stating that it was included in the fund’s year-end report. He also noted that the donor PAC had not reported the contribution in its own filing but plans to amend it.

Despite the relatively small amount involved, the inquiry adds a layer of scrutiny at a sensitive moment in the race. The FEC has given the committee until May 6 to respond or correct the filing, warning that failure to comply could “result in an enforcement action against the committee.”

Such inquiries are not uncommon and rarely lead to serious penalties. However, in a competitive race, even minor issues can be used as political ammunition.

That dynamic is especially notable given that Cornyn himself previously used similar concerns to attack Paxton. Last year, Cornyn’s campaign highlighted a federal inquiry into Paxton’s financial filings, suggesting it showed a pattern of questionable practices. That inquiry involved $658,000 in potentially illegal contributions.

Since then, Paxton’s campaign has faced additional scrutiny, including inquiries into nearly $100,000 in donations flagged in a recent filing and $125,000 in contributions questioned earlier this year.

A bitter runoff battle takes shape

The race between Cornyn and Paxton has grown increasingly tense, with both sides escalating their attacks as the runoff approaches. The contest has also drawn attention from national figures, including President Donald Trump, who has hinted that he may endorse one of the candidates.

So far, Trump has not made a decision, leaving both campaigns to compete for his backing. His potential endorsement is seen as a key factor that could shape the outcome.

Meanwhile, outside groups have already begun to weigh in. A pro-Paxton super PAC, Lone Star Liberty, launched ads targeting Cornyn in Palm Beach, Florida, where Trump frequently stays. One ad delivered a direct attack, declaring, “John Cornyn betrayed President Trump, and he doesn’t deserve our trust.”

Paxton has not yet released his fundraising numbers for the first quarter of 2026, leaving an open question about how his campaign compares financially. His filings are due April 15.

As the runoff election draws closer, both candidates are expected to ramp up spending and messaging, making the contest one of the most closely watched political battles in Texas.

For Cornyn, the path forward is defined by both opportunity and risk. His campaign has built a strong financial foundation, but the emergence of federal questions—however routine—adds uncertainty to an already volatile race.

With millions of dollars at stake, a divided Republican base, and national attention focused on the outcome, the coming weeks will likely determine not only the nominee, but the direction of the party in one of its most important strongholds.
