BREAKING: Liz Cheney DEFEATED in Wyoming

Rep. Liz Cheney was defeated in the Wyoming GOP primary Tuesday by Trump-endorsed attorney Harriet Hageman. Decision Desk HQ projected Hageman's win shortly after the polls closed. At the time the race was called, Hageman was leading with 58.54 percent of the vote to Cheney's 38.03 percent.

Former President Donald Trump won the state in 2020 with nearly 70 percent of the vote. Heading into the primary, Cheney trailed Hageman by nearly 30 points in a University of Wyoming poll published Thursday.

Cheney said in a speech to supporters following her loss that she had called Hageman to concede the race.

Cheney has been a vocal critic of Trump and was one of the 10 Republicans who voted to impeach then-President Trump following the riot at the US Capitol on Jan. 6, 2021. She has also served as vice chair of the House select committee investigating the riot and has lost the support of many Republicans since taking office in 2017.

In a last-ditch effort to win, Cheney attempted to court Democrat voters based on her anti-Trump record. Yet some Democrats, such as former Hawaii Congresswoman Tulsi Gabbard, celebrated Cheney's defeat.

Her father, former Vice President Dick Cheney released an ad for his daughter and called Trump a "coward."

"In our nation’s 246-year history, there has never been an individual who is a greater threat to our republic than Donald Trump. He tried to steal the last election using lies and violence to keep himself in power after the voters had rejected him."

"He is a coward. A real man wouldn't lie to his supporters. He lost his election and he lost big. I know it, he knows it and deep down I think most Republicans know it."

Earlier Tuesday, Cheney, standing next to her father, told CBS News after casting her vote, "Today, no matter what the outcome is, is certainly the beginning of a battle that is going to continue. We’re facing a moment where our democracy really is under attack and under threat. And those of us across the board, Republicans, Democrats, and independents who believe deeply in freedom and who care about the Constitution and the future of the country, have an obligation to put that above party."

Former President Donald Trump posted on Truth Social following Cheney's defeat, "Congratulations to Harriet Hageman on her great and very decisive WIN in Wyoming. This is a wonderful result for America, and a complete rebuke of the Unselect Committee of political Hacks and Thugs. Liz Cheney should be ashamed of herself, the way she acted, and her spiteful, sanctimonious words and actions towards others. Now she can finally disappear into the depths of political oblivion where, I am sure, she will be much happier than she is right now. Thank you WYOMING!"

On Monday, The New York Times editorial board praised the "principled stand" against former President Donald Trump that Cheney took along with Sen. Lisa Murkowksi (R-AK). Murkowski is also facing a strong primary challenge Tuesday night.

In her concession speech to supporters Tuesday night Cheney teased a possible bid for the White House. After stating that Abraham Lincoln lost congressional races before being elected President, Cheney said, "now the real work begins."

"The great and original champion of our party Abraham Lincoln was defeated in elections for the Senate and the House before he won the most important election of all," Cheney said in her speech.

Lynnette Grey Bull won the Democratic nomination for the House in Wyoming's at-large Congressional District Tuesday night and will go up against Hageman in the general election in November.
