Iowa ‘ag gag’ law is challenged as unconstitutional
A coalition of consumer, free speech and animal rights groups filed suit in federal court in Des Moines to challenge the constitutionality of Iowa's "ag gag" law, enacted in 2012. Iowa is the No. 1 state for hog and egg production and the largest target yet by campaigners against state laws that criminalize undercover employment on farms and at packing plants.
