Elon Musk appeared visibly distressed during a Fox Business interview, discussing the difficulties in managing his multiple ventures amid Tesla's 15.4% stock drop. Investors are worried about Musk's political involvement distracting him from Tesla,

Unelected White House advisor and president Donald Trum's closest buddy Elon Musk isn't too happy about having abandoned his businesses.
