Tesla CEO Elon Musk appeared to be cognizant of toeing the line between being confrontational and likable during his testimony Monday in the securities trial against the executive and his electric vehicle company.

The trial in San Francisco federal court stems from his 2018 tweets announcing he planned to take Tesla private for $420 per share. During voir dire, some potential jurors lambasted Musk as narcissistic and arrogant, with several pointing directly to the layoffs at Twitter Inc. following Musk’s ownership of the social media giant.
