Shares in Tesla have fallen on reports that US regulators are seeking to question executives at the firm about its privatization plans.
Fox News tweeted that the US Securities and Exchange Commission (SEC) had sent subpoenas to the electric carmaker and was “ramping up” its investigation.
Mr Musk announced on Twitter on 7 August that he was considering taking Tesla private at $420 (£330) a share, and that “funding [is] secured”
There is still many questions about how Mr. Elon Musk can finance taking the firm private at the price he tweeted. There is buzz that Saudi may be in the mix.
