From the Daily News:
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.
