A federal judge disclosed Friday that former presidential candidate John Edwards has a life-threatening heart condition, a court source confirmed to CNN. Edwards had sought a delay in his criminal corruption trial, scheduled to begin this month. Attorneys and the federal judge met in a North Carolina courtroom Friday afternoon for a status hearing regarding the pending trial of Edwards, a former U.S. senator. Edwards appeared at Friday's hearing. His lawyers had made the motion for a delay under seal, but some of its details were publicly revealed by the judge in the open hearing.
