*This post has been updated to include Lt. Gov. Mike Stack's statement.

The findings of a state Inspector General's office investigation into complaints of mistreatment of staff at the lieutenant governor's residence by Lt. Gov. Mike Stack and his wife Tonya will remain a secret.

Gov. Tom Wolf told reporters on Tuesday he is not going to release that report.

Stack responded to that news in a statement: "My family is grateful for the support from the governor, as well as from family and friends across Pennsylvania as we address this private family health issue. We are more committed than ever to make sure that every Pennsylvanian has access to the same quality health care that is available to us."

Gov. Tom Wolf called on Inspector General Bruce Beemer last spring to investigate allegations of verbal abuse and demands that the lieutenant governor's security detail use their sirens in non-emergency situations.

Shortly thereafter, Wolf took what is believed to be an unprecedented step of removing the state police security detail assigned to Stack and his wife. The governor also ordered staff to perform groundskeeping and maintenance duties at the lieutenant governor's residence at Fort Indiantown Gap only at prearranged times and with supervision.

"My concern back in the summer was to make sure the employees, the police officers, the staff at the residence were safe and were not in a bad job situation and I took care of that," Wolf said on Tuesday. "I don't think anything is to be served by piling on top of that."

After the mistreatment complaints came to light, Stack held a news conference where he apologized to his staff for how he and his wife Tonya treated them.

"Both of us are deeply sorry for offending anybody and we're going to make it up for everybody because we feel we can make it better," Stack, 54, told reporters inside his office. "People in public life, public officials, have a higher standard."

While he didn't believe his actions were abusive to staff, Stack admits he did say things "in anger and stress and frustration that I wish I hadn't."

The Philadelphia Inquirer later reported that Stack's wife had begun in-patient treatment for a mental health issue.

Wolf indicated on Tuesday that he wanted to be fair to Stack's wife, who he thought is still undergoing treatment.

"There's no reason to go any further than I did," he said.

The controversy continues to dog Stack but has not interfered with his intention to seek re-election to his second-in-command post next year. Wolf and Stack do not have a close relationship as some past governors and lieutenant governors have enjoyed and didn't run as a team in 2014.

Wolf has not offered any indication that he intends to endorse Stack's candidacy for the second-in-command post that has drawn a field of five other declared candidates so far seeking to be the Democratic nominee for lieutenant governor.
