Cleveland Clinic knew surgeon was accused of raping patients but kept him on staff, USA TODAY investigation finds. The Cleveland Clinic, one of the nation's largest and most renowned hospitals, knew of at least two cases in which one of its surgeons was accused of raping patients but kept him on the staff while reaching a confidential settlement, a USA TODAY investigation has found. Ryan Williams, a colorectal surgeon accused in police reports by two women of anally raping them in 2008 and 2009, left the Cleveland Clinic last summer for Ohio State University Medical Center, which has placed him on leave after learning of the complaints against him.
