Elizabeth Edwards is opening up a new front in the battle with her husband, John. After legally separating from him, she is now threatening to sue his former aide, Andrew Young, for helping her husband conduct his affair with campaign videographer Rielle Hunter. North Carolina is one of only seven states where a third party may be sued for the dissolution of a marriage. Unless Young agrees to several terms, including a $250,000 donation to the Wade Edwards Foundation and a promise to stop discussing the Edwards' marriage, she intends to pursue the suit, according to ABC News. Young's busy legal team is also dealing with a complaint from Hunter, who claims that a sex tape she made with Edwards is her property. Young turned it over to a North Carolina court on Wednesday.
