President Obama has already asked Hagan to start looking for Holding's successor. But during a conference call Wednesday, Hagan said now is not the time to replace him.
"I've talked to the White House about it. That's up to the president. I don't want to politicize this. I do think, it is my feeling that George Holding should stay on until these investigations are over with," she said.
On Monday, North Carolina Republican leader Linda Daves said Holding is leading the charge against corruption in state government and replacing him now with a Democrat with ties to the Easley administration would send the wrong signal.
