The independent investigator hired by Gov. Andrew Cuomo’s administration to review Buffalo Billion contracting will speak to “hundreds” of people in his inquiry, the governor on Thursday told reporters in western New York.

At the same time, Cuomo said the state could potentially adjust how it spends economic development money based on the findings of Bart Schwartz, the former prosecutor hired to review contracting in the program, which is under scrutiny by the U.S. attorney’s office.

“When we get the results of the inquiry, if there are lessons to learn, changes to make, we’ll do that,” Cuomo said, adding, “Our investigator will talk to hundreds of people, but it’s about the actions of several people.”

Cuomo’s former top aide and confidant, Joe Percoco, is being eyed for his role in economic development programs, while he’s also received consulting feeds from companies with business before the state. At the same time, lobbyist Todd Howe, who worked as a go-between with SUNY Polytechnic, is under scrutiny as well.

Cuomo announced the hiring of Schwartz last month after acknowledging his office had received a subpoena as part of the investigation.

Scwhartz will make his report public unless the information conflicts with the ongoing work of U.S. Attorney Preet Bharara.

Letters from Cuomo officials have said Schwartz will have final approval over contracting in the program going forward. A contract for Schwartz detailing how much he is being paid and outlining his duties is yet to be released.

“We are very aggressive in taking those questions seriously,” Cuomo said. “We will tolerate no impropriety.”

The governor also defended the economic development spending in western New York, primarily for SolarCity, a company whose finances have fallen under question. The state is paying for the construction of a SolarCity factory at the RiverBend site in western New York.

“We’re very excited about SolarCity and Riverbend and all the projects that are bringing back jobs to western New York,” Cuomo said. “Simple fact: This state has had more private sector than it’s ever had in its history.”
