(Reuters) -Amazon.com Inc, an early backer of Rivian Automotive, now owns about a fifth of the electric-truck maker, the e-commerce giant disclosed in a quarterly filing on Friday.
Ford Motor Co, which has a strategic relationship with Rivian, removed a representative from the startup's board earlier this month.
