EXCLUSIVE — A Democrat running against Rep. Elissa Slotkin (D-MI) for Michigan’s open Senate seat is piling on to Republican criticism of the lawmaker’s alleged ties to a Chinese-linked company.

Hill Harper, a black actor and long-shot primary opponent of the establishment-backed Slotkin, brought up accusations she signed a nondisclosure agreement to discuss a proposed Michigan plant by Chinese-affiliated electric vehicle battery maker Gotion, according to video obtained by the Washington Examiner.
