Gov. Andrew Cuomo acknowledged on Monday evening his former top aide Joe Percoco had told him he planned to take on additional consulting work while also working on his re-election campaign.

While Cuomo was aware Percoco would be taking on additional work outside of government, he was not told of the specifics.

“Joe left state service and went into the private sector,” Cuomo said. “He consulted for my campaign. I knew he might be accepting consulting jobs for other companies.”

Percoco, a longtime confidant for Cuomo, is at the center of a corruption investigation stemming from a key economic development project in western New York, the Buffalo Billion.

“I’m saying I know Joe Percoco for many years and he is a good man and I would be shocked if he did anything wrong,” Cuomo told reporters in New York City. “But let’s get the facts and then we can all make a decision.”

Financial disclosure filings made available on Monday by the Joint Commission on Public Ethics show Percoco was receiving as much as $125,000 in consulting fees from companies that have business before the state, including COR Development. The company has contracts related to the Buffalo Billion program.

Percoco’s wife also received consulting work from a LLC that has ties to businesses with state contracts as well.

Cuomo said it’s “totally allowable” for someone to leave the state payroll, as Percoco did in 2014 to run the re-election effort, and take on private consulting work.

“It was consulting,” Cuomo said. “He was serving as a consultant for my campaign and he said he might be doing consultant work for other clients.”

Cuomo has spoken with Percoco in recent days, saying the matter is a “deeply troubling situation.”

Percoco is not just any other government aide. He’s a deeply trusted member of the Cuomo inner circle who started work in the public sector with Cuomo’s late father, then-Gov. Mario Cuomo.

Percoco has worked with Cuomo in a variety of capacities, including his time at the Department of Housing and Urban Development as well as the state attorney general’s office.

The conversation, Cuomo said, was on a “personal basis” and that Percoco is “distraught and his family’s distraught. It’s painful. It is a very painful thing.”

“Joe and his family, his wife and his kids I know very well,” Cuomo said. “This is just a terrible situation for him first of all, for his family. It’s terrible. I don’t know another word for it. I think it’s very important the facts come out, because right now we have a lot of questions, we have a lot of questions, but we have very few facts.”

The federal investigation has reportedly focused on Percoco, as well as lobbyist Todd Howe, who has represented before the state SUNY Polytechnic, a key player in high-tech businesses that are being wooed to upstate New York.

At the same time, a company that is seeking to build a power plant in Orange County is being eyed by federal investigators.

The Buffalo Billion itself has been a key program for Cuomo, who has frequently touted the economic gains made in western New York during his time in office.

“It’s important for me to be able to say to the people of the state of New York the Buffalo Billion is being run well and their tax dollars are being protected,” Cuomo said. “Buffalo is buzzing in a way it hasn’t been buzzing in a long time. I want to say to the people of this state you should have confidence in the way this program is being operated because we have the best mind brought in to investigate, soup to nuts.”
