Texas, nine other states, 22 members of the U.S. House of Representatives and the National Rifle Association 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 Texas Attorney General Ken Paxton and colleagues from Alabama, Arkansas, Georgia, Louisiana, Oklahoma, South Dakota, Utah 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.
