bhararaComptroller Tom DiNapoli in a radio interview on Thursday described his relationship with the office of U.S. Attorney Preet Bharara’s office as “ongoing and positive” as the federal government investigates the contracting process for the “Buffalo Billion” economic development program.

DiNapoli wouldn’t say, however, whether he or his office has been issued a subpoena or turned over documents relating to Bharara’s investigation.

“I can’t comment directly on that question other than to say we have a very on going and positive relationship with Mr. Bharara’s office,” he said on Fred Dicker’s Talk-1300 radio show. “Certainly it’s a cooperative one. But I can’t comment without any specificity about those interactions.”

Bharara and DiNapoli were spotted last year breaking bread in lower Manhattan, a lunch that came after the federal prosecutor took possession of records generated by the Moreland Commission, an anti-corruption panel that folded earlier in 2014 following an agreement on ethics law changes in the state budget.

Attorney General Eric Schneideramn, along with DiNapoli, have also teamed up on various public integrity probes in recent years.

DiNapoli, a Democrat, has a chilly relationship with Gov. Andrew Cuomo, whose administration has placed an emphasis on the Buffalo Billion program, an economic development plan aimed at creating 14,000 jobs in western New York through state and private-sector investment.

In the interview, DiNapoli said his office would continue its auditing of state contracts, and even borrowed a line from Bharara.

“Like any place we have to set our priorities. We don’t have unlimited resources,” he said. “We have a lot of audits going on at the state level, at the local level. But we are going to continue look at the various economic development programs. I would say as we often do these days ‘Stay tuned.'”
