In the book, “This Will Not Pass: Trump, Biden, and the Battle for America’s Future,” Martin and Burns wrote that the elder Cheney — who served as the at-large congressman from Wyoming from 1979 to 1989 before becoming the US Defense secretary under President George H.W. Bush and then vice president under President George W. Bush — commended his daughter’s decision to chastise Trump.

“Among the elder statesmen proudest of Liz Cheney was her father, the former Vice President, who made it clear to friends that he looked on his daughter’s vote with admiration and assent. Trump, Dick Cheney said, was ‘a maniac,'” Martin and Burns wrote.
