Regulatory Scrutiny Known for his Twitter banter, announcements and lively interactions with followers, Musk has had his share of run-ins with financial regulators.

The SEC also asked him to step down as chairman. Investors will keep an eye on any response from the regulators on Elon Musk's Twitter poll, especially since the regulator had ordered Tesla to vet any material public communications Musk made regarding the EV maker, following his 2018 tweet.
