On March 4, 2010, the Federal Transit Administration issued an Audit of the State Safety Oversight (SSO) program overseeing Metro which criticised the SSO as being underfunded and poorly trained. In response, Virginia, Maryland and the District of Columbia have increased their SSO funding and training for their employees responsible for safety oversight at Metro. Jackson Graham, a retired general in the Army Corps of Engineers who supervised the planning and initial construction of the Metrorail system, was the first general manager. Graham retired in 1976, and was replaced by Theodore C. Lutz. Richard S.
