The National Rifle Association, Georgia, nine other states and 22 members of the U.S. House of Representatives filed seven amicus briefs in the U.S. Supreme Court on Tuesday and Wednesday on behalf of Remington Arms Co. LLC, which seeks to have the court rule that a federal law shields it from liability.

The gun maker, which manufactures the AR-15 rifle used in the 2012 Sandy Hook Elementary School mass shooting, got support from Georgia Attorney General Chris Carr and colleagues from Alabama, Arkansas, Louisiana, Oklahoma, South Dakota, Utah, Texas and West Virginia, plus the governor of Mississippi. It asked the U.S. Supreme Court to hear its appeal of a Connecticut high court ruling favoring families and survivors who sued over the shooting.
