Tesla CEO Elon Musk slammed Wedbush Global Head of Technology Research Dan Ives on twitter telling him to "shut up" after Ives suggested the board limit Musk's political activity. The tweet comes during a turbulent week that saw shares in the electric vehicle-maker plunge after the billionaire businessman announced he's forming a new political party.

Dan Ives, a longtime Tesla bull, brushed off Elon Musk's viral "shut up" remark, saying he just wants it to spark healthy dialogue about the CEO's focus and remains committed to pressing for greater board oversight.

Tesla CEO Elon Musk has been a harsh critic of President Donald Trump's spending bill. Trump said Musk had "gone off the rails."
