The state's acting treasurer has said the commonwealth spent about $100,000 complying with the federal investigation into former Treasurer Rob McCord.
McCord pleaded guilty last month to two federal charges that he tried to shake down potential donors to give to his gubernatorial campaign or risk losing business or perks with the commonwealth.
"No agency chief counsel wants to spend funds on an investigation," said Christopher Craig, executive deputy state treasurer and chief counsel. "However, these matters have to be and demand to be taken extremely seriously."
Craig said no public money was used for McCord's legal representation.
Gov. Tom Wolf has not yet selected a replacement to finish McCord's term through 2016.
