Sen. Elizabeth Warren of Massachusetts wrote to the Securities and Exchange Commission on Monday, urging it to investigate Tesla (TSLA.O) and its board of directors for "conflicts of interest, misappropriation of company assets" related to Musk's acquisition of Twitter, Jinse Finance reported. and other negative effects on Tesla shareholders". Warren said Musk may have "violated state and federal labor laws" by taking Tesla employees to Twitter and that Tesla's board had not properly informed shareholders of how the two companies were or could be working together. Warren also said that the appointment of Linda Jacarino as Twitter CEO effectively still puts Musk in charge of Twitter, an arrangement that may lead to a conflict of interest. Musk could "maximize Twitter's much-needed revenue, even if that includes offering big deals to Tesla's competitors and potentially hurting Tesla," or he could choose to "generate through favorable algorithms or free advertising." Run Twitter to benefit Tesla."
