The Securities and Exchange Commission is looking into whether Tesla CEO Elon Musk tweeted about taking the company private in order to hurt those who were shorting Tesla's stock, according to a report in the Wall Street Journal Thursday.

The agency is pressing Tesla's board for details on how much information he shared with them prior to announcing his plans on Twitter, the report said, citing a source. Two key questions are what Musk may have told directors before he spoke publicly about the possibility of taking Tesla private and when he spoke to them.
