Republican House minority leader Kevin McCarthy was booed Saturday afternoon in Casper, Wyoming, during a Donald Trump rally. The heckling almost immediately rang out as McCarthy appeared virtually to endorse Liz Cheney’s MAGA-loving (and Trump-endorsed) primary challenger Harriet Hageman. “Hello, Wyoming. I’m Kevin McCarthy, ”he said as Trump supporters began booing him. McCarthy’s office did not return The Daily Beast’s request for comment on Saturday night. Last month, tensions between Trump and McCarthy boiled over after The New York Times published tapes of the minority leader vowing to push Trump to step down as president after the January 6 Capitol riot.
