A top official who supervises key library and police projects for the District of Columbia’s troubled contracting office has been suspended, a source told The Examiner.

Karen Hester, a commodity manager in the Office of Contracting and Procurement, was relieved of her duties last week after a meeting with Assistant Director Esther M. Scarborough, a source in the office told The Examiner. The source spoke on condition of anonymity because of a fear of retribution from supervisors.
