The new leader of the national Black Lives Matter non-profit “siphoned” more than $10 million in fees from donors to pay his consulting firm, according to a lawsuit. But the BLM leader, Shalomyah Bowers, told The Post the case against him is nothing more than a power grab by disgruntled activists trying to wrest control of the movement. Bowers, who became head of the Black Lives Matter Global Network Foundation in April, is accused of paying the cash to his own Bowers Consulting Firm, and diverting resources from a new group called Black Lives Matter Grassroots, Inc.
