Politico reported they’re “furious” and told the outlet: “It’s clear he has abused the proximity to the president.” The recent frustration centered on Trump’s announcement this week of a joint venture investing up to $500 billion for infrastructure tied to artificial intelligence. Trump declared it “a resounding declaration of confidence in America’s potential” under his new administration, with an initial private investment of $100 billion that could reach five times that sum. But Musk, a close Trump adviser who helped bankroll his campaign and now leads a government cost-cutting initiative, questioned the value of the investment hours later. “They don’t actually have the money,” Musk wrote on his social platform X. “SoftBank has well under $10B secured. I have that on good authority.” From Politico: A White House official said Musk “very much” got over his skis when the tech tycoon launched a daylong screed against the AI project. One Trump ally said Musk abused his closeness to the president. Another Republican close to the White House went further, saying Trump’s staff is “furious” over Musk using his massive social media platform to pour cold water on the infrastructure deal that Trump called “tremendous” and “monumental” just a day prior. “It’s clear he has abused the proximity to the president,” said the Trump ally. “The problem is the president doesn’t have any leverage over him and Elon gives zero fucks.” It is highly unusual for a senior adviser — Musk — to criticize a president’s initiatives in public, and his broadsides renewed speculation within GOP circles about whether he and Trump will eventually have a falling-out. Musk has had seemingly unparalleled access to Trump during the transition since he parked himself at Trump’s side in Mar-a-Lago and heads Trump’s so-called Department of Government Efficiency.
