Senator John Cornyn has a message for Republican voters: if the GOP loses the House in the 2026 midterms, Democrats will impeach President Trump for a third time.
Cornyn made the case on NewsNation’s “The Hill Sunday,” arguing that a Democratic House majority would grind Trump’s legislative agenda to a halt and launch impeachment proceedings all over again.
The warning is real enough on its merits.
Democrats impeached Trump twice during his first term, and there is no reason to believe they would not try again with a House majority.
Holding the chamber is essential to protecting the Trump agenda through 2028.
But the timing of Cornyn’s media blitz is impossible to ignore.
The Texas GOP Senate runoff is tomorrow. Cornyn is facing former Texas Attorney General Ken Paxton, who received President Trump’s endorsement last week.
As The Texas Tribune reported, Trump’s endorsement of Paxton landed like a thunderclap in the race:
The impeachment warning started spreading quickly as the runoff clock ticked down:

Cornyn has spent the final days of the runoff trying to argue that his seniority and institutional relationships make him more effective at advancing Trump’s priorities.
Sunday’s impeachment warning fits neatly into that pitch. The implication is clear: keep me in the Senate because I know how to protect the president.
The problem for Cornyn is that Republican voters do not appear to be buying it. A Quantus Insights runoff poll conducted after Trump’s endorsement of Paxton shows the former AG leading Cornyn by double digits.
Paxton leads Cornyn 53% to 43% in that survey, a margin that suggests Trump’s endorsement may have effectively settled the race.
The late polling picture added another layer to the Texas fight:

Cornyn is right that losing the House would be a disaster for the Trump agenda.
That is a straightforward political fact.
A Democratic majority would weaponize committees, block legislation, and yes, almost certainly pursue impeachment.
But framing yourself as Trump’s indispensable ally while the president himself just endorsed your opponent is a tough sell, especially the night before the vote.
Texas Republicans will have their say tomorrow. The impeachment warning may be Cornyn’s strongest argument, but right now, Trump’s endorsement of Ken Paxton looks like the stronger card.
Breitbart reported Cornyn’s warning from the NewsNation interview this way:
Cornyn made the warning during NewsNation’s “The Hill Sunday,” according to Breitbart.
He said he supports President Trump because he wants the president to be successful, wants America to be successful, and wants the Republican Party to be successful.
ADVERTISEMENTCornyn said he would continue voting in that same direction, but argued the president sometimes needs help, especially as Republicans look toward the midterms.
He warned there is more anxiety about the midterms than people may fully appreciate.
Cornyn said the midterms will be critical to the last two years of President Trump’s term.
His bluntest line was that if Republicans lose the House, President Trump will likely get impeached for a third time.
ADVERTISEMENTHe added that a House loss would make it virtually impossible to pass the president’s legislative agenda.
Cornyn then said he wants to continue helping the president where he can.
He also argued he is the strongest Republican to run against Democrat James Talarico.
Cornyn called Talarico a Bernie Sanders-style Democrat and said Texas is not going backward without a fight.
The Associated Press put the Texas runoff fight in this final-day context:
Cornyn and Texas Attorney General Ken Paxton entered the final day before Tuesday’s Texas GOP Senate runoff.
Their fight for the nomination has stayed intense and heavily driven by advertising.
Paxton’s campaign and supportive groups had shifted their closing message to emphasize President Trump’s May 19 endorsement.
ADVERTISEMENTPresident Trump later reaffirmed his support for Paxton and criticized Cornyn as insufficiently loyal.
Trump described Paxton as loyal to him while calling Cornyn very disloyal.
Cornyn, in response, leaned into his own support for the president.
Cornyn said 99.3 percent of his Senate votes aligned with Trump.
Cornyn’s campaign has argued Paxton would struggle in November and could put the seat at risk against Democrat James Talarico.
Paxton’s side has leaned on the Trump endorsement as the final-hours unity message.
That context is what makes Cornyn’s impeachment warning more than a stray television line.
The Texas Tribune detailed President Trump’s endorsement and what it meant inside the race:
The Texas Tribune reported President Trump endorsed Paxton in the Republican runoff for U.S. Senate in Texas.
The endorsement ended more than a year of lobbying and gave Paxton a major boost against Cornyn.
President Trump called Paxton a true MAGA Warrior who had always delivered for Texas.
Trump said Cornyn was a good man and that they worked well together, but said Cornyn was not supportive when times were tough.
ADVERTISEMENTTrump also criticized Cornyn for being late to back his 2024 presidential bid.
Paxton said he was honored by the endorsement and looked forward to championing President Trump’s America First agenda in the Senate.
The Tribune reported Cornyn finished first in the March primary with 42 percent, while Paxton had 40.5 percent.
The runoff became a test of loyalty, electability, and who Texas Republicans trust to carry the MAGA agenda into November.
Cornyn’s latest argument is that he can help protect President Trump’s agenda from a Democratic House.
Paxton’s argument is that President Trump has already chosen the fighter he trusts.
Quantus Insights framed the late polling picture this way:
Quantus Insights published a final survey titled “Paxton Holds Edge on Eve of Texas GOP Runoff.”
The page description said the final survey found President Trump’s endorsement widely known among the electorate.
It also said Paxton’s advantage rested on broader runoff alignment.
270toWin summarized the Quantus survey on X as Paxton 53 percent and Cornyn 43 percent after President Trump’s endorsement.
That is polling context, not an election result.
The runoff itself is scheduled for Tuesday, May 26, 2026.
The numbers do show why the closing message matters.
Paxton is trying to convert President Trump’s endorsement into a decisive MAGA turnout advantage.
Cornyn is trying to convince voters that the larger stakes include the Senate seat, the House map, and President Trump’s ability to govern during the final two years of his term.
That is the political collision now landing in front of Texas Republican voters.
