Tesla’s new chairman Robyn Denholm has defended the use of Twitter by CEO Elon Musk. “Twitter is nowadays part of the daily activities of many business people,” Denholm said in an interview in Sydney. “In my view, he uses it wisely.” Denholm was appointed as chairman after Musk had to give up that position as a result of a settlement with stock market regulator SEC. The watchdog tackled Musk after he had told Twitter to want to take Tesla off the stock market and to have the funds for it, even though it wasn’t true. Musk also had to pay a fine and was no longer allowed to twitter market-sensitive information. Musk did the latter again according to the SEC when he tweeted a production number for Tesla. Musk denies and believes the SEC is exaggerating the case. The two will be on trial in New York on Thursday 4 April.
