A former United Auto Workers board member charged with conspiring with other union leaders to embezzle hundreds of thousands of dollars of rank-and-file members’ dues is scheduled to appear in federal court in Detroit on Tuesday. The court appearance of Vance Pearson, 58, comes just days after General Motors Co filed a racketeering lawsuit against Fiat Chrysler Automobiles NV (FCA) in connection with a spreading corruption probe, accusing its rival of bribing UAW officials to gain advantages at GM’s expense.
