Impeachment Republicans' last stand? Cheney, Murkowski face Trump-backed primary challengers

In her final campaign video ahead of Tuesday's Wyoming GOP primary in the battle for the state's single House seat, Rep. Liz Cheney condemns Donald Trump and tells viewers that the "lie that the 2020 presidential election was stolen is insidious" and has been used to "manipulate Americans to abandon their principles, to sacrifice their freedom, to justify violence, to ignore the rulings of our courts and the rule of law."

"This is Donald Trump's legacy," she continues, "but it cannot be the future of our nation. History has shown us over and over again how these types of poisonous lies destroy free nations."

Despite the lengthening odds against Cheney beating her Trump-endorsed opponent, Harriet Hageman, the ousted House Republican Conference chair has been unwavering in her anti-Trump messaging.

Last year, Cheney was removed from her position as the third-ranking House Republican when she emerged as the face of the her party's small anti-Trump faction. She was formally censured by the Republican National Committee in February.
