Cassidy during an interview that aired Sunday on "Axios on HBO” said that he did not believe Trump would be the GOP presidential nominee again.

“President Trump is the first president, in the Republican side at least, to lose the House, the Senate and the presidency in four years. Elections are about winning,” Cassidy told Axios’s Mike Allen.

When Allen noted that it was "clear" that Cassidy would not be voting for Trump in any case, Cassidy responded, "I'm not."

In a statement on Monday, Trump called Cassidy a "RINO," an acronym for "Republican in name only," and reiterated a notion he had hoisted on other Republicans that Cassidy had "begged" for his endorsement in 2020 "and used it all over the place to win re-election."

"Now, Wacky Bill Cassidy can’t walk down the street in Louisiana, a State I won by almost 20 points," the Trump statement read. "He could not even be elected dog catcher today, the great people curse him."

Cassidy was among the seven Republican senators who voted to convict Trump for inciting an insurrection at the Capitol on Jan. 6, though Trump was ultimately acquitted after leaving office later that month.
