WASHINGTON (AP) — President Donald Trump is threatening to cut Elon Musk’s government contracts as their fractured alliance rapidly escalated into a public feud. Hours after Trump lamented his breakup with Musk and said Thursday that he was “disappointed” in his former backer and adviser and Musk responded on social media, Trump then escalated the feud by threatening to use the U.S. government to hurt Musk’s bottom line.
