Elon Musk, having just left Donald Trump’s team after the end of his 100-day contract leading the DOGE, now appears to have effectively declared war on Trump’s budget, which the president has dubbed the “Big Beautiful Bill.”

Beyond simply criticizing it, Musk is now urging people to call their Senators and Representatives to pressure them not to approve the budget. This will certainly not please Donald Trump, who has been working hard in recent weeks to secure its passage.
