Elon Musk Breaks Ranks with Trump, Torches Navarro in Tariff Tirade: “He Ain’t Built Sh—”
In a fiery outburst that stunned political and economic circles alike, Elon Musk has publicly broken with the Trump administration on its aggressive tariff policies—taking direct aim at White House trade czar Peter Navarro in the process.
The billionaire tech titan, still reeling from an $11 billion loss in personal wealth after a market nosedive sparked by Trump’s new global tariffs, didn’t hold back in his criticism.
Musk lit up X (formerly Twitter) on Saturday with a string of barbed posts targeting Navarro, one of the chief architects of Trump’s protectionist trade agenda.
“A PhD in Econ from Harvard is a bad thing, not a good thing,” Musk jabbed, taking aim at Navarro’s academic credentials. “Results in the ego/brains >> 1 problem,” he added, implying inflated ego and misplaced intelligence.
When another user chimed in to defend Navarro, Musk doubled down with a brutal retort: “He ain’t built sh—.”
The remarks mark a rare public rift between Musk and the Trump administration, with whom he has shared an occasionally cordial, often complex relationship. But the recent announcement of sweeping tariffs—impacting virtually every U.S. trading partner—appears to have pushed the SpaceX and Tesla CEO over the edge.
Musk voiced his preference for open global trade, calling instead for a “zero tariff situation” between the U.S. and Europe, starkly contrasting the isolationist bent of current policy.
The fallout from Trump’s tariff decree has been swift. Global markets tumbled, and Musk’s own companies—Tesla and SpaceX—saw shares dip sharply, contributing to a multi-billion-dollar blow to his fortune.
While Navarro has not responded publicly to Musk’s tirade, insiders say tensions between Silicon Valley power players and Washington’s trade hawks have been simmering for months.
With Musk’s comments now fanning the flames, the clash between tech and Trumpworld may just be heating up.
