"Firstly I think I must for the record refer to the events that have taken place over the last few weeks," he said. "I wish to reiterate and reaffirm the statements already made on my behalf by Buckingham Palace. My focus is my work."
Roberts filed a sworn affidavit in federal court on Wednesday adding new details to her claims and vowing "to pursue all reasonable and legitimate means to have criminal charges brought against these powerful people for the crimes they have committed against me and other girls."
A statement from the British royal family earlier this month called her allegations "false and without any foundation," and a spokesman for the royal family declined Wednesday to respond to Roberts' new affidavit.
Epstein, an enigmatic financier, was the subject of wide-ranging state and federal investigations beginning in 2005 looking into claims that he had illegal sexual contact with dozens of girls at his Palm Beach mansion and elsewhere. He ultimately entered into an unusual and, at the time, confidential non-prosecution agreement with the federal government that resulted in him pleading guilty to two relatively minor sex crimes in state court. Dershowitz was among a group of prominent attorneys who helped Epstein secure the deal.
Dershowitz has also strongly denied her allegations.
"Every single word in her affidavit about me is a deliberate and categorical lie. I don't know her, I was never with her, I never touched her," Dershowitz told ABC News on Wednesday.
Dershowitz said he wants Roberts to come forward with dates and times on their alleged encounters so he can use his travel records to prove his innocence, he said.
"She picked on the wrong innocent person, because I have the will, the determination and the resources to fight back and prove that what she's saying is false,” he said.
