President Trump's decision to endorse Texas Attorney General Ken Paxton against incumbent Sen. John Cornyn has reignited fears among Senate Republicans that his escalating campaign against GOP critics could backfire, making it harder to advance his legislative agenda.
Trump's support for Paxton, announced Tuesday, marks the latest move in what many see as a retribution tour targeting Republican lawmakers who have crossed him. Earlier this month, Trump helped oust Sen. Bill Cassidy in Louisiana and Rep. Thomas Massie in Kentucky, signaling his willingness to punish party members who defy him.
Sen. Thom Tillis (R-N.C.) warned that undermining incumbents like Cornyn could cost Trump the supermajority support needed for controversial measures, including funding for a proposed White House ballroom. "Why would anybody think that that makes sense?" Tillis asked, noting that a loss for Cornyn would leave Trump with a narrow majority and emboldened dissenters.
Senate Majority Leader John Thune (R-S.D.) echoed those concerns, cautioning that Trump's vendettas complicate the already delicate task of securing votes. "There's always a consequence associated with taking on incumbent United States senators," Thune said, while acknowledging Trump's right to endorse candidates.
Cornyn, who served as Senate Republican whip and helped enact Trump's tax cuts and confirm his nominees, expressed disappointment but remained confident. "We've got the best team and the best plan of any election I've ever run in," he said, declining to speculate on the impact of Trump's feud.
The rift comes as Trump pushes for a budget reconciliation package that includes funding for a White House ballroom, a project that has drawn criticism even from allies like Cassidy, who called it a "slush fund." The internal GOP tensions threaten to stall Trump's broader agenda, particularly on healthcare and energy policy.
Sen. Lisa Murkowski (R-Alaska) noted that Trump seeks loyalists in Congress, but she questioned whether the strategy would yield long-term results. "I'm not suggesting that the president's endorsement of Paxton over a principled, strong, solid lawmaker is wise," she said.
As the Texas runoff approaches, the outcome will test Trump's sway over GOP voters and his ability to maintain party unity. For now, Senate Republicans are bracing for a potentially costly showdown that could reshape the political landscape.
