U.S. officials interviewed convicted sex trafficker Ghislaine Maxwell while her legal team awaits a Supreme Court decision on her 20-year prison sentence appeal.

A senior administration official confirms to NBC News that Ghislaine Maxwell was granted limited immunity by the Justice Department in order to answer questions about the Jeffrey Epstein case. This type of immunity allowed Maxwell to answer questions from Deputy Attorney General Todd Blanche without fear that the information she provided could later be used against her in any future cases or proceedings.
