Last July, Wyoming Republican Harriet Hageman drove seven hours from her home in Cheyenne to Jackson to meet with a major donor who wanted her to wage a primary campaign against Donald Trump’s top nemesis, GOP Rep. Liz Cheney.

When Hageman arrived for the breakfast meeting the following morning, she was greeted by a surprise guest: former Trump White House chief of staff Mark Meadows. Hageman had heard from an array of Wyoming Republicans urging her to take on Cheney. But Meadows was dialing up the pitch, making the case for Hageman to jump in and putting her on the phone with Ohio Rep. Jim Jordan, another staunch Trump ally who reinforced the point. After leaving the breakfast, Meadows called Trump and encouraged him to meet with the soon-to-be candidate, according to a person familiar with the discussion.

The episode illustrates Trump’s all-encompassing role in the effort to oust Cheney, which culminated Tuesday in a lopsided primary defeat for the congresswoman. Hageman ran with Trump’s support, was advised by Trump’s lieutenants, and was funded by his donors. Trump aides vetted and interviewed Cheney’s prospective challengers with a degree of care the operation didn’t display in other big midterm races. Once they settled on their pick, they cleared the field of Hageman’s primary rivals. Then, the team formed an outside group that was heavily funded by Trump’s PAC, which ran TV ads starring the former president’s son, Donald Trump Jr.
