Jeff Hurd

President Trump on Friday reversed himself and re-endorsed Representative Jeff Hurd, Republican of Colorado, an unusual move that came a month after he pulled his support from Mr. Hurd over a disagreement about tariffs.

Mr. Trump’s previous decision to withdraw his endorsement from Mr. Hurd and back his right-wing primary opponent, Hope Scheppelman, concerned some Colorado Republicans. They saw her as a divisive figure who could endanger the party’s chance of holding the seat in the general election if she advanced past the primary.

In a statement on social media on Friday, Mr. Trump said Ms. Scheppelman would be leaving the campaign to join his administration in a “capacity to be determined.” The president added that Mr. Hurd “should in no way, shape, or form, be impeded from winning” re-election in his conservative-leaning swing district, which covers much of the western half of Colorado.

“I will be fully supporting Jeff’s Re-Election to the House of Representatives, giving him my Complete and Total Endorsement!” Mr. Trump wrote. “Every true MAGA supporter and Republican, if they truly care about saving our Country, will do everything in their power to unify together.”

Just a month ago, Mr. Trump appeared to cast his move against Mr. Hurd as a warning to other Republicans who might resist his tariff policies. He posted in early February that any lawmakers who supported lifting the levies would “seriously suffer the consequences come Election time, and that includes Primaries.”

Mr. Hurd said Friday that he was grateful for the Mr. Trump’s support. “The President and I share the same goals: securing the border, American energy dominance, and helping working families,” he said in a statement, adding that he would continue to run “a serious campaign.”
