Shares of electric-truck maker Nikola Corp tumbled as much as 30% on Monday after founder Trevor Milton stepped down following claims of nepotism and fraud by a Wall Street short-seller that have drawn interest from U.S. regulators. GM, which recently announced it would receive an 11% stake in Nikola under a partnership, said in a statement on Monday it would work with Nikola to close the deal while stressing it was just one element of its electric vehicle strategy.
