An ethics committee for the Atlanta school board will investigate statements allegedly made by board chairman Reuben McDaniel about former chairwoman Brenda Muhammad. The commission voted Friday to look into a complaint from Atlanta parent and attorney Cynthia Briscoe Brown. According to Brown, McDaniel said Superintendent Erroll Davis had concerns about Muhammad’s handling of vendor matters. Muhammad called the allegations untrue. The commission will take sworn statements from board members and Davis regarding the matter.
