GREENSBORO, N.C. (AP) -- Prosecutors have asked a federal judge in North Carolina to bar those in the upcoming trial of former presidential candidate John Edwards from mentioning his poor health because of concern it could create sympathy among jurors.

Edwards' trial was delayed in January after his lawyers said the Democrat needed treatment for a serious heart condition. Jury selection is to begin April 12.

Prosecutors also asked for an order limiting any mention before the jury of possible pending contempt charges against former Edwards' aide Andrew Young stemming from a lawsuit over possession of a sex tape made by the candidate's mistress. Young is expected to be a key witness for prosecutors against Edwards, who has pleaded not guilty to charges related to campaign finance violations.
