The White House has shrugged off a spat between President Trump’s trade adviser Peter Navarro and the world’s richest man, Elon Musk. On Tuesday, Musk used his social media site X to hurl insults at Navarro, calling him a “moron,” “Peter Retarrdo” and “dumber than a sack of bricks,” after Navarro defended Trump’s sweeping tariffs and described Tesla as “not a car manufacturer” but “a car assembler.” The Washington Post reports Musk has repeatedly tried — and failed — to pressure Trump to reverse the tariffs. On Tuesday, White House Press Secretary Karoline Leavitt dismissed the feud.

Press Secretary Karoline Leavitt: “Boys will be boys, and we will let their public sparring continue. And you guys should all be very grateful that we have the most transparent administration in history.”
