As pressure builds for Grady Memorial Hospital CEO Pam Stephenson to answer questions regarding her law degree, efforts are under way to oust her as chairwoman of the Atlanta hospital's authority board. Some state and local officials have criticized Stephenson for the multiple hats she's donned in Grady management, saying they represent conflicts of interest. The latest controversy over her law degree is adding momentum to efforts to remove her as the Grady authority chairwoman. The 10-member board will soon meet to elect its officers. While it remains unclear whether there are enough votes to oust her as chairwoman, some authority members say Stephenson's controversies have become a distraction from overseeing the business of Grady.
