Rep. Liz Cheney launched a new campaign ad Thursday pushing that "truth" regarding the 2020 election should win and calling out her political rivals for embracing the big lie, calling it a "cancer." "As Election Day nears, I want to talk to citizens across our great state and country. America cannot remain free if we abandon the truth," Cheney stated, looking into the camera as she stood in a wildflowers field. "The lie that the 2020 presidential election was stolen is insidious."

She doubled down on that criticism Thursday, denouncing Trump and Republicans who have pushed that the FBI's raid of Mar-a-Lago Monday has to be somehow corrupt. "I have been ashamed to hear members of my party attacking the integrity of the FBI agents involved with the recent Mar-a-Lago search," she tweeted. "These are sickening comments that risk patriotic public servants' lives." In the ad, she called the ex-president's wrong election fraud allegations a "door Donald Trump opened 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." [tweet_embed] August 13, 2022[/tweet_embed] "This is Donald Trump's legacy, but it cannot be the future of our nation," she announced. "History has shown us over, and over again these types of poisonous lies destroy free nations." She then aimed her anger at her election rivals - mainly Harriet Hageman, the Trump-supported candidate beating her in a University of Wyoming's Wyoming Survey and Analysis Center poll, issued Thursday, by 29 points. "Like many candidates across this country, my opponents in Wyoming have said that the 2020 election was rigged and stolen," Cheney announced. "No one who understands our nation's laws, no one with an honest, honorable, genuine commitment to our Constitution, would say that." [tweet_embed] August 13, 2022[/tweet_embed] "It is cancer that threatens our great Republic," the Republican congresswoman warned. "If we do not condemn these lies, if we do not hold those responsible to account. We will be excusing this conduct and it will become a feature of all elections," she said. 'America will never be the same." Cheney claimed that nothing is more important "than the preservation of the miracle given to us by God and our founding fathers."
