The former mistress of John Edwards wants a North Carolina judge to issue a contempt order against a one-time Edwards campaign aide in a case involving a purported sex tape.

Lawyers for Rielle Hunter filed a motion Wednesday in Orange County Superior Court asking for a contempt-of-court finding against Andrew and Cheri Young and their lawyer.

Hunter's motion claims the Youngs have shared information with federal prosecutors in a separate criminal case involving Edwards. Her lawyers say that violates protective orders in the civil case.

Hunter is suing the Youngs for the return of various items, including a purported sex tape featuring Edwards, the former North Carolina senator and 2004 Democratic vice-presidential nominee.

Young has said he helped cover up Edwards' affair during his 2008 presidential bid and worked to keep Hunter in hiding.
