Some of President Donald Trump's key aides and allies are furious with Elon Musk for publicly trashing his $500 billion artificial intelligence mega-deal. 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."
