U.S. Senator Elizabeth Warren has asked Tesla's board to investigate whether CEO Elon Musk is using the electric carmaker's resources to benefit other companies he owns and operates. In a 10-page letter sent to Tesla Chairperson Robyn Denholm on Thursday, the Democratic senator said Musk's actions, such as transferring computer chips from Tesla to his social media company, X Corp., may have been inappropriate. Musk confirmed in June that he was redirecting artificial intelligence chips ordered for Tesla to X Corp. and xAI Corp., saying they would otherwise remain in warehouses. Ms Warren argued that moving the chips could be a "misappropriation of company resources" and said the creation of xAI itself was an "inevitable conflict of interest" for Mr. Musk.
