Widow of Rep. Elijah E. Cummings is among 24 Democrats seeking his seat in Congress. : For years, Maya Rockeymoore Cummings ran a charity so closely intertwined with her for-profit consulting firm that they shared the same employees, the same office space and the same director — her. The private firm carried out the charity’s mission of promoting public health and addressing racial and economic inequity under a cost-sharing agreement that gave the firm a 5 percent management fee. Rockeymoore Cummings signed a contract on behalf of both parties to set up the unusual relationship.
