When former Wyoming representative Liz Cheney criticized Donald Trump's presidency, she says she didn't know the Republican party would turn on her. But after losing her leadership role in the party and her bid for reelection, Cheney had to reassess. Her new book, Oath and Honor, opens up about the House investigation into the January 6 attack, and her colleagues' ambivalence on impeaching Trump. In today's episode, Cheney tells NPR's Leila Fadel why she thinks it's important to talk about Trump's effort to overturn the 2020 election, and how it can still pose a threat to democracy in 2024.
