"In 2009, Giuffre and Epstein reached a confidential settlement in a lawsuit she filed against him, which has been sealed ever since. Last month, according to documents on file in federal court, Giuffre dropped her claim of sexual battery she made in a separate lawsuit against lawyer
Alan Dershowitz, who formerly represented Epstein, after
Dershowitz invoked this part of the 2009 settlement agreement. "
For all we know there could have been others covered by the 2009 Settlement,(Dershowitz was covered by the settlement agreement because he was one of Epstein's attorney) and there could have been others that settled with her with a confidentiality agreement.
