"In so doing, Benjamin abused his authority as a New York State senator, engaging in a bribery scheme using public funds for his own corrupt purposes," said prosecutors in the indictment. The investor, meanwhile, was arrested on federal charges in November.

Benjamin, Gov. Kathy Hochul's #2, surrendered to federal authorities Tuesday morning.

The indictment followed a joint investigation by the US attorney for the Southern District of New York, the city's Department of Investigation and the FBI.

Benjamin admitted to The Post that he was interviewed in connection with the conspiracy and wire fraud charges filed in November against Harlem landlord and lawyer Gerald Migdol, who's accused of making illegal, "straw" donations to Benjamin's campaign.

In November, Migdol was arrested for allegedly orchestrating a scheme to funnel illegal campaign contributions to Benjamin's unsuccessful 2021 bid.
