Fresh Start PA, a political-action committee founded to support Wolf's bid for governor, does much of the negative campaigning against Corbett.
"Clearly it is time for the governor to come clean on this matter," said McGinty, who called for an independent investigation into Tomalis. "Instead of putting forth evidence of the work he was doing, there has been a desperate effort at a coverup to create a story line about what Mr. Tomalis has been doing."
That's a reference to Dumaresq, who told the Pittsburgh Post-Gazette there were few work emails from Tomalis because her department routinely deletes emails every day. The newspaper yesterday reported that is a violation of the department's own policy on document retention.
Chris Pack, a spokesman for Corbett's re-election campaign, called McGinty's demands "just another desperate attack" from Wolf's campaign.
Mark Nicastre, a spokesman for Wolf's campaign, suggested Corbett had given Tomalis a "no-show job."
"It's Harrisburg at its worst, and Governor Corbett has a lot of explaining to do," Nicastre said.
Dumaresq, in a statement announcing Tomalis' resignation, said he "has truly been an asset to me and the department."
In his resignation letter, Tomalis did not mention the controversy directly but suggested he was looking for a new job.
He wrote: "As you know, I have been engaged in conversations with other organizations regarding new opportunities, and given recent events, I believe it is in the best interest of the administration that I resign my position with the Commonwealth, effective Aug. 26, 2014, to pursue those endeavors."
