An investigation into whether John Edwards illegally funneled funds from his presidential campaign to cover up an affair with a staffer who bore his love child intensified this week, as federal investigators subpoenaed a host of new witnesses to appear before a grand jury, sources close to the investigation say. The grand jury in Raleigh, North Carolina has been investigating Edwards, accused of providing a love nest for mistress Rielle Hunter for over a year.
At the conclusion of an initial investigation into whether Edwards used contributions to hide away Hunter and staffer Andrew Young, Justice Department officials in Washington instructed local investigators to keep digging, interviewing more people to find out exactly who donated money, sources told ABC News affiliate WTVD-TV.
