A federal subpoena has been issued requesting records from self-proclaimed "super mayor" Tiffany Henyard and others as authorities pursue a criminal investigation tied to the ousted mayor.

The subpoena was signed on Feb. 25, the day Henyard, a Democrat, lost the mayoral primary in Dolton, Illinois, by a landslide. The subpoena is tied to a development project involving land once reportedly owned by Henyard's boyfriend, FOX 32 Chicago reported.

The summons demanded a number of documents from 2014 until now, including copies of citations, code violations, emails, phone calls and text messages between property owners, tenants and village personnel. It also requested correspondence between property owners, tenants and village of Dolton personnel. The personnel included Henyard's boyfriend, Kamal Woods.
