The chairman of Southern University’s Board of Supervisors resumed his duties on Tuesday, after an internal investigation last month cleared him of allegations that he had sexually harassed female employees, according to The Advocate, a newspaper in Baton Rouge, La. The board chairman, Johnny G. Anderson, who is also assistant chief of staff to Gov. Kathleen Babineaux Blanco, stepped down voluntarily in April to remove the appearance of “improprieties” while the university-system board considered reports of sexual harassment. The board cleared Mr. Anderson after the investigation could not substantiate the claims against him. Tuesday’s meeting was also the first attended by Southern’s president, Ralph Slaughter, since he returned from a two-month suspension. The board had placed Mr. Slaughter, who made the sex-harassment allegations public, on leave during the investigation. Mr. Slaughter is suing the Board of Supervisors, Governor Blanco, and others for allegedly conspiring against him for acting as a whistle-blower. —Karin Fischer
