An Illinois state senator was formally accused of collecting a salary as well as health and pension benefits from a labor union “for which he did little or no work” by a federal grand jury Friday in Cook County. Villa Park Democrat Tom Cullerton, who has served in the General Assembly since January 2013, is charged with 40 counts in an indictment alleging he “knowingly conspire(d)” to embezzle from the Teamsters Joint Council 25 and Teamsters Local Union 734 Unions.
