PHILADELPHIA — The ex-headmistress of Oprah Winfrey's school for girls in South Africa sued the TV talk show host for defamation, claiming Winfrey falsely suggested she tried to cover up abuse at the school. In widely reported remarks last year, Winfrey suggested that Nomvuyo Mzamane, 39, of Philadelphia, knew about alleged abuse by a dorm matron and tried to cover it up, Mzamane says in the lawsuit. Her lawsuit, filed in Philadelphia Common Pleas Court on Friday, seeks more than $250,000 on five defamation and related counts from Winfrey and her production company. More...
