In September, electric-car company Nikola inked a $2 billion deal with General Motors to produce an electric pick-up truck.
But two days later, things began to unravel.
A short seller revealed that it gathered "extensive evidence" that it said indicated fraud and implicated founder Trevor Milton. Nikola called the short seller's findings "false and misleading," but soon after, the SEC and the DOJ began examining the allegations.
Milton resigned from the company, but around the time of his resignation, two women, one of whom was Milton's cousin, came forward alleging that he had sexually assaulted them, which Milton denied.
Then, at the end of September, a report surfaced alleging Milton had bought the designs for the Nikola semi-truck rather than designing it himself, as he had previously claimed.
By November, GM said it would no longer take a stake in Nikola or produce a consumer truck, but will still sell its hydrogen fuel cells to the company.
