Internet reports that Tesla CEO Elon Musk has sharply escalated his attack on Trump's senior trade adviser Peter Navarro, defending his car company and being annoyed by the government's tariff plans. "Tesla has the most American-made cars. Navarro is dumber than a bag of bricks,"Musk, Trump's top campaign donor, wrote on X, the social media platform he owns. "Navarro is such an idiot. What he said here is clearly wrong,"Musk wrote in another post.（CNBC）
