President Donald Trump threatened Saturday to back a primary challenger to Rep. Lauren Boebert (R-CO) after she campaigned in Kentucky for Trump adversary Rep. Thomas Massie (R-KY).“Is anyone interested in running against Weak Minded Lauren Boebert in Colorado’s Fourth Congressional District?” Trump said in a Truth Social post. “Even though I long ago endorsed Boebert, if the right person came along, it would be my Honor to withdraw that Endorsement, and endorse a good and proper alternative.”Boebert is among a small group of GOP lawmakers who have publicly supported Massie in his race against Trump-backed Ed Gallrein, a former Navy SEAL and Army Ranger. Sen. Rand Paul (R-KY) was also at the event.
Massie has emerged as one of Trump’s most outspoken critics on high-profile policy debates, including Trump’s handling of the Jeffrey Epstein case, the Iran war, and spending.
Gallrein held roughly a 5 percentage-point lead over Massie one day before early voting began, according to a Wednesday Quantis Insights poll of 908 likely GOP voters. The primary will be held on Tuesday, May 19.
Trump had endorsed Boebert in 2024 when he was a presidential nominee, calling her then a “Proven Conservative” who delivers for the “America First agenda.” She has been a notable ally of Trump in Congress, recently introducing legislation in late April to give congressional approval to Trump’s White House ballroom.
