Some of the contours of the inquiry were made clear in a federal grand jury subpoena served on the State University of New York Polytechnic Institute, which has played a central role in administering the governor’s program, known as the Buffalo Billion. The subpoena was one of a number issued in recent months, according to people with knowledge of the matter. One of the other subpoenas went to Empire State Development, New York State’s economic development agency, which is providing funding for the program.
People with knowledge of the subpoena to SUNY Polytechnic, who spoke on the condition of anonymity because they were not authorized to speak publicly about the matter, described its contents in detail to The New York Times.
One area of interest, according to these people, was a 2013 request for proposals that was written in a way that would have disqualified many possible bidders, and favored a construction company whose chief executive had donated tens of thousands of dollars to Mr. Cuomo. The subpoena also sought information about the hiring of staff members who would develop requests for proposals and distribute funds for Buffalo Billion projects.
