JACKSON, Wyo. In a defeat that many of her supporters acknowledged was inevitable, Wyoming Rep. Liz Cheney, one of former President Donald Trump s fiercest GOP antagonists, lost her Republican primary on Tuesday to a Trump-endorsed opponent, attorney Harriet Hageman.

Cheney, a three-term congresswoman representing the nations reddest state, crossed the GOP base as well as her Republican colleagues when she voted with Democrats to impeach Trump for instigating the Jan. 6, 2021, riot at the U.S. Capitol.

The vote cost Cheney her spot as the No. 3 Republican in the U.S. House, and the speakership she was thought at one time to be eyeing.

I will do whatever it takes to ensure that Donald Trump is never anywhere near the Oval Office, and I mean it, Cheney said Tuesday night as she conceded the election, adding: I love my country more.

Cheney also served as the top Republican on the House select committee investigating the Jan. 6 attack, a role that earned her an unprecedented rebuke from the Republican National Committee.
