Rep. Liz Cheney told CNN she's "very worried" about election deniers running for office in 2022.
43 election-denying candidates are seeking statewide office in 27 states, one report found.
"I think those people have all got to be defeated," Cheney said.
Arizona, Michigan, and Alabama have such candidates running for all three of those offices in November.
"That's obviously, fundamentally, a threat to the survival of the republic, and I think those people have all got to be defeated," Cheney said.
