They request an interview to clarify the nature of his relationship with Epstein.
"This would, of course, allow you to fully respond in a dignified manner and appropriate setting that would, we believe, clarify the record for everyone's benefit, including your own," they wrote in the letter.
Outside court in Manhattan, Roberts said of Prince Andrew: "He knows what he has done and he can attest to that. He knows exactly what he's done - and I hope he comes clean about it."
