Puccio resigned at the end of last year. He is now the chairman of the state Democratic Party.
Investigators are also, according to WSAZ, looking into work done on the governor's office by Clark Diehl, a wallpaper man who pleaded guilty to bypassing the contract bidding process and is cooperating with authorities.The Department of Administration has also reportedly been subject to subpoena.
A special attorney general appointed to the case, Dwayne Tinsley, told Politico he couldn't reveal many details.
"However, as far as I know, little has changed with the investigation," Tinsley said. "I am still working with state agencies to gather and provide information to the federal government. To my knowledge, no one working for the State, past or present, is the focus of this or any investigation."
