In the aftermath of the 2020 presidential election, Donald Trump and many around him, including certain other elected Republican officials, intentionally breached their oath to the US Constitution: they ignored the rulings of dozens of courts, plotted to overturn a lawful election, and provoked a violent attack on the Capitol. Liz Cheney, one of the few Republican officials to take a stand against these efforts, witnessed the attack first-hand, and then helped lead the Congressional Select Committee investigation into how it happened. In Oath and Honor, she tells the story of this perilous moment in US history, those who helped Trump spread the stolen election lie, those whose actions preserved the constitutional framework, and the risks the US faces and the worldwide implications.
