RALEIGH, N.C. (AP) - A Wake County grand jury has indicted former campaign workers and a donor of North Carolina Gov. Beverly Perdue as part of an investigation into previously undisclosed flights leading up to her 2008 election victory. Grand jurors handed up indictments Monday in state court against Trawick H. "Buzzy" Stubbs Jr., Peter Reichard and Juleigh Sitton. The charges come more than a year after Wake County prosecutor Colon Willoughby said he would investigate payments of air travel for the campaign following a State Board of Elections probe of Perdue's campaign committee. The State Board of Elections fined her committee $30,000. Perdue is seeking re-election in 2012. A grand jury in February charged a Morganton man over allegations he deceived Perdue's campaign by hiding the source of money used for a flight.
