He has attacked the network in turn — most recently, he criticized them for firing its star host, Tucker Carlson — and still holds a grudge over its projection on election night in 2020 that he would lose Arizona. Fox was the first network to do so.
His decision to appear on a rival network, CNN, is a signal to Fox, which is a crucial pipeline to Republican primary voters: He doesn’t consider it the only game in town. The move is also a way of drawing a sharp contrast with one of his expected opponents in the race, Gov. Ron DeSantis of Florida, who largely shuts out the mainstream media.
Lately, Mr. Trump has fumed about the release of private emails that show how Rupert Murdoch, chairman of Fox Corporation, expressed derision and contempt for him and his false claims of being cheated in the 2020 election. Those messages were released as part of the defamation lawsuit that Dominion Voting Systems filed against the network for amplifying conspiracy theories that Dominion machines were somehow involved in a plot to steal votes from him and flip them to President Biden.
Mr. Trump lashed out at Mr. Murdoch and Fox for “aiding & abetting the DESTRUCTION OF AMERICA” on his social media platform, Truth Social.
Mr. Trump also plans to skip at least one of the first two debates with his rivals for the 2024 Republican nomination, according to several people familiar with his plans. The first, scheduled for August in Milwaukee, is being hosted by Fox News. He has said he does not want to give the lower-polling G.O.P. candidates the oxygen that a nationally televised debate would provide.
