As Elon Musk ends his stint at the White House, major Tesla shareholders have rallied, calling on the CEO to refocus his attention on the electric vehicle company amid its declining sales and shares.

Yesterday (May 28), Tesla chair Robyn Denholm received a letter signed by 12 major pension funds that collectively hold significant stakes in the company. As first reported by the Financial Times, the letter calls on Musk to commit to working at least 40 hours per week at Tesla.

Tesla investors demand Elon Musk commit full-time amid falling profits, weak sales, and growing leadership concerns.
