What Jamie Dimon, Bill Ackman, and other CEOs and billionaires are saying about Trump’s trade war

Even the world’s most prominent Trump supporter, Elon Musk, is displeased with the tariffs.
Musk, who runs the Department of Government Efficiency (DOGE), spent the weekend criticizing the administration’s top trade adviser, Peter Navarro, and amped up his criticism Tuesday, saying Navarro is “dumber than a sack of bricks.”
Navarro had gone on TV on Monday to suggest that Musk’s issues with Trump’s tariffs were because Musk’s Tesla (TSLA) automobiles were made with parts primarily from outside the U.S. Navarro noted that many of Tesla’s car parts come from Japan, China, Mexico, and Taiwan, all of which will be hit hard by Trump’s tariffs.
“He’s a car person,” Navarro said. “That’s what he does, and he wants the cheap foreign parts.”
Musk said Tuesday on X that “Tesla has the most American-made cars” and that, “By any definition whatsoever, Tesla is the most vertically integrated automaker in America with the highest percentage of US content.”
Musk has heavily criticized the Trump administration’s universal and reciprocal tariff plan and has appealed to the president to walk back the levied duties. Two sources told the Washington Post that Musk personally made an attempted tariff-related appeal to Trump — but has been unsuccessful in changing the president’s mind thus far.
