CHICAGO (AP) — A bipartisan panel of Illinois lawmakers voted Thursday to postpone grilling people connected with Gov. Pat Quinn’s anti-violence program, bowing to the wishes of the U.S. Justice Department, which has a criminal investigation underway.

Though the Legislative Audit Commission bickered for hours Wednesday over how to proceed, members voted unanimously to call seven subpoenaed witnesses Oct. 8, complying with the 90-day respite requested by U.S. Attorney James Lewis in Springfield. Lewis feared testimony before the commission would jeopardize his probe.
