CHICAGO, Ill. (IRN) — A coalition of 20 Democratic state attorneys general, including Illinois Attorney General Kwame Raoul, are backing a federal gun rule in court.

The Final Rule, as the Bureau of Alcohol, Tobacco, Firearms, and Explosives named it, would enable law enforcement officials to trace any homemade guns used in crimes. In addition, the rule limits trafficking the weaponry.
