New York City Councilman Miguel Martinez
City Councilman Miguel Martinez resigned Monday as prosecutors revealed he's agreed to plead to federal charges after an extensive probe of a nonprofit group to which he steered more than $500,000.
The Manhattan U.S. attorney's filed notice a criminal information will accuse Martinez of a crime as early as Tuesday. It would be the first criminal charges against a Council member in the city slush fund scandal.
The notice doesn't disclose the charges, but indicates Martinez has agreed to plead guilty to the unspecified accusations.
A Martinez ally and other sources said the charges involve the nonprofit group Upper Manhattan Council Assisting Neighbors (U-CAN), which received city member-item funding through Martinez.
Martinez' sister was once a U-CAN board member. In March, the city's Department of Investigation seized records from U-CAN's offices, as part of a broader investigation into possible abuses of City Council member item funding.
Two weeks later, City Council officials yanked $528,000 in funding to U-CAN earmarked for the fiscal year that ended June 30.
Martinez had repeatedly denied knowing of misuse of funding by U-CAN.
He had been in the process of seeking reelection to another four-year term, made possible by the Council's decision late last year to extend term limits.
The vacancy will be filled in this year's September primary and November general elections.
