The Duke of York said in a statement Saturday that “at no stage during the limited time I spent with him did I see, witness or suspect any behavior of the sort that subsequently led to his arrest and conviction.” Epstein was convicted in 2008 after pleading guilty to prostitution-related state charges and served 13 months behind bars.
