Andy Cunningham, a longtime Silicon Valley communications professional who once worked with Steve Jobs and now leads her own marketing agency, the Cunningham Collective, said she heard from a concerned Tesla shareholder last year.

Tesla CEO Elon Musk was coming off a hectic 2018, in which he was criticized for smoking cannabis on a popular podcast. He also tweeted erratically at times. He tweeted that he was taking Tesla private and that he had secured funding when the SEC said he had not, which led to a $40 million fine, $20 million for Musk personally and $20 million for the company.
