Am considering taking Tesla private at $420. Funding secured. — Elon Musk (@elonmusk) August 7, 2018 Musk skipped his tendency to tweet in response to news of the lawsuit—arguably, his erratic, uncensored behavior on Twitter is the reason both Musk and Tesla are in hot water—and Tesla responded with a statement on behalf of the CEO on Thursday. "This unjustified action by the SEC leaves me deeply saddened and disappointed. I have always taken action in the best interests of truth, transparency and investors. Integrity is the most important value in my life and the facts will show I never compromised this in any way," Musk wrote. This added to an earlier statement released by Tesla in which Musk said he was "saddened and disappointed" by the SEC charges. Following the announcement of the SEC charges, Tesla stock plunged in after market trading. Musk is also being sued by a major short seller for his tweets about taking Tesla private.
