Why not Trump! Tesla CEO Elon Musk to the SEC: Don't 'Trample' on My Free Speech -- Lawyers for Tesla CEO Elon Musk fired back at the Securities and Exchange Commission late Monday, arguing that a push to hold Musk in contempt of court for a Twitter post last month infringed on his First Amendment rights. In a filing Monday night, Musk's lawyers said Musk's tweet complied with the terms of a September settlement agreement between the Teslafounder and the SEC. "Since entry of the Order, Musk has dramatically reduced his volume of tweets generally and regarding Tesla in particular," his lawyers said. "This self-censorship is reflective of his commitment to adhering to the Order and avoiding unnecessary disputes with the SEC." On Feb. 19, Musk tweeted: "Tesla made 0 cars in 2011, but will make around 500k in 2019." Following Musk's Twitter post last year that he had "funding secured" to take Tesla private, a settlement with the SEC "required more "controls and procedures to oversee Musk's communications." The SEC said Musk's Feb. 19 tweet was inaccurate, and that he did not seek nor receive pre-approval prior to publishing. Musk had until Monday to explain why he shouldn't be held in contempt of court. Musk's lawyers argued this push was an "invitation to trample on Musk's First Amendment rights and grant the SEC far broader powers than authorized by Congress."
