Senator Elizabeth Warren has called for an SEC investigation into Tesla over Elon Musk's acquisition of Twitter last year, citing potential conflicts of interest and misappropriation of corporate assets. Warren accused Tesla's board of inadequate disclosures and inaction, raising concerns about the effectiveness of the board's corporate governance and potential violation of securities laws. She also suggested that Musk's relationships with board members may have contributed to their inaction. Tesla is set to report Q2 financial results this week.
