RALEIGH, NC (WTVD) -- The state investigation into Bev Perdue's campaign for governor is nearing an end, and the man in charge of that investigation said it would likely end with new charges being filed.
Wake County District Attorney Colon Willoughby said Gov. Perdue was not under investigation, nor was any other public official, but said his investigation has grown beyond where it started.
"There's certainly conduct that has given us pause and concern," he said.
Willoughby talked at length about his investigation into flights taken by then-Lt. Gov. Perdue that were not paid for on time - in some cases, years later.
In August 2010, the North Carolina Board of Elections fined the Perdue campaign $30,000 for "flight irregularities," but then Willoughby began his own investigation and more than a year later he said his work is just a few weeks from finished.
"I think, pretty soon, the investigative part of it will be over and the only decision left will be for me to try to make decisions as to what charging decisions will be appropriate," he said.
However, Willoughby said his investigation has gone beyond just flight irregularities.
