A day after he announced his support of a 23-state coalition asking the U.S. Supreme Court to allow a Ten Commandments display on First Amendment grounds, Georgia Attorney General Chris Carr said Thursday he has joined a 21-state coalition defending the rights of gun owners under the Second Amendment.

“It is the duty of the Office of the Attorney General to uphold and defend the rights and liberties of our citizens under both the U.S. and Georgia Constitutions,” Carr said in a news release. “The Second Amendment gives law abiding citizens the right to not only keep, but also to bear, arms and we joined this brief because the Fourth U.S. Circuit Court of Appeals inappropriately adopted an unduly restrictive view of the Second Amendment.”

The coalition filed a brief on Friday asking the Supreme Court to hear a challenge to a Maryland weapons ban. The brief argues that the ban infringes on Second Amendment rights by prohibiting the sale, transfer and possession of a class of firearms that are in common use for lawful purposes, Carr said.
