Colorado Republican Rep. Ken Buck won't run for re-election to the U.S. House in 2024, he announced Wednesday.

In a video to constituents, Buck criticized the GOP for what he called the "insidious narratives" that the 2020 presidential election was stolen, and prosecutions following amounted to weaponization of the Justice Department.

Buck said he believed the GOP needed to return to conservative principles instead of "self-serving lies." 

"To my friends in Colorado, thank you for allowing me the opportunity to serve our nation, and to serve you," Buck said in a statement. "I look forward to seeing you at the grocery store and the high school football game. Being your representative in Washington, DC, has been the greatest professional thrill, and highest honor, of my life."
