Donald Trump ranted about Vice President Dick Cheney and his daughter, former Rep. Liz Cheney (R-Wyo.), on Friday after the two threw their support behind Vice President Kamala Harris’ campaign this week.

“Dick Cheney is an irrelevant RINO, along with his daughter, who lost by the largest margin in the History of Congressional Races!,” wrote the GOP nominee on his Truth Social platform.

His post comes on the same day that Liz Cheney revealed that her father, who once endorsed Trump’s 2016 campaign before becoming a harsh critic of the former president, would be voting for the Democratic nominee in the fall.

Dick Cheney, who served as former President George W. Bush’s VP, later released a statement confirming that he’s backing Harris and warned that Trump can “never be trusted with power again” due to his efforts to overturn the 2020 election results.

Trump, in his Truth Social post, railed about Dick Cheney not pardoning his ex-chief of staff I. Lewis “Scooter” Libby who in 2007 was convicted of four felony charges of perjury and obstruction of justice related to a CIA leak scandal.

“They couldn’t get Scooter Libby, who did so much for them (but was so unfairly treated!), PARDONED. I did it!” wrote Trump, who pardoned Libby in 2018 (Bush did not pardon Libby and later claimed that the decision made his VP “angry”).

Trump continued, “He’s the King of Endless, Nonsensical Wars, wasting Lives and Trillions of Dollars, just like Comrade Kamala Harris. I am the Peace President, and only I will stop World War III!”

He went on to criticize Liz Cheney for her work as former vice chair of the Jan. 6 committee before pushing a number of false claims about the committee and who was “responsible” for security at the Capitol on the day of the deadly riot.

Dick Cheney, with his Harris endorsement on Friday, joined a number of Republicans formerly on the GOP presidential ticket who have signaled they won’t be voting for Trump in November.
