With investigations dogging both his administration and that of Mayor Bill de Blasio, Governor Andrew Cuomo on Tuesday addressed the controversy surrounding the so-called Buffalo Billion economic development project and what he called the mayor’s grand conspiracy theory. Bobby Cuza filed the following report.

Without actually naming him, Mayor Bill de Blasio has for weeks implied Governor Andrew Cuomo is behind the investigations into his fundraising on behalf of state Senate Democrats.

Tuesday, after an event rolling out new MTA buses, Cuomo was asked if he played a role.

"The only thing I know about the investigations on the mayor is what I read about in the newspaper," Cuomo said. "And look, it may all be a grand conspiracy against him, but then the U.S. attorney, the attorney general of the state of New York, the Manhattan district attorney are all part of a conspiracy."

But Cuomo’s administration, too, is under the cloud of investigation, as U.S. Attorney Preet Bharara looks into possible improprieties related to the so-called Buffalo Billion economic development project. A Wednesday vote by a state oversight panel to approve $485 million in additional funding on Buffalo’s SolarCity project was abruptly postponed. Cuomo said it was a scheduling issue, and stressed his office is conducting its own internal investigation and that he’ll do everything he can to maintain the integrity of state government.

"If and when something bad happens, we will have zero tolerance for any abuse. We will throw the book at anybody who does anything wrong," Cuomo said.

Yet Cuomo also seemingly downplayed Bharara’s investigation, noting most of the investigations he started as attorney general never led anywhere.

"You get a tip, God bless you. Follow it up. That’s just what I did as attorney general. That’s what the U.S. attorney should be doing," Cuomo said. "Because there’s a question doesn’t mean anyone did anything wrong."

Cuomo was also asked about the prospects for ethics reform in Albany, where there’s no been movement on the issue despite the conviction and recent sentencing of the legislature’s two top former leaders on corruption charges.

"My agenda was very sweeping. I don’t believe we’ll get the entire agenda," Cuomo said. "I do believe we will get some ethics reform."
