Ghislaine Maxwell, the former girlfriend of Jeffrey Epstein, urged the Supreme Court on Monday to take up her pending appeal and overturn her sex-trafficking conviction, claiming she was covered by an agreement Epstein made with federal authorities that shielded her from prosecution.

The new filing responds to a Justice Department brief that argued the justices should leave Maxwell's criminal convictions in place.

James Comer, chairman for the House Committee on Oversight and Government Reform, on Wednesday issued a subpoena for Ghislaine Maxwell, according to a press release from his office.
