The Securities and Exchange Commission subpoenaed electric-vehicle maker Tesla (NASDAQ:TSLA) over a settlement that required founder and CEO Elon Musk's tweets to be investigated, Reuters reported, citing a disclosure in an annual filing with the SEC. The subpoena came after Musk ignited a selloff in TSLA stock after asking his Twitter (NYSE:TWTR) followers in November if he should liquidate 10% of his TSLA stake, Reuters said. The SEC's latest action added to Tesla's (TSLA) regulatory pressure regarding auto recalls and investigations in its driver assisting software. In December the Department of Justice asked TSLA to provide the agency with information regarding Musk's prior statement that he considered taking Tesla private, in addition to Model 3 production rates, according to the company's 2021 annual report. With regards to Tesla's bitcoin (BTC-USD) holdings, the company held $1.99B worth of BTC as of Dec. 31, 2021, Reuters reported. It registered about $101 million
