A group of mostly red states filed a brief with the nation's high court on Tuesday seeking to rule Washington's "high capacity" magazine ban unconstitutional.

Led by Montana Attorney General Austin Knudsen, these states submitted a 32-page amicus brief to support the plaintiffs in Gator's Custom Guns v. State of Washington. The plaintiffs challenge Washington's magazine capacity ban, which had been upheld by the Washington Supreme Court in May. 

"The Supreme Court needs to step in to uphold Americans’ right to keep and bear arms," said Knudsen. "Lower courts, including the Washington Supreme Court, are attempting to attack and rewrite the Second Amendment."

Knudsen argues that, "Washington’s restrictions burden the rights of millions of law-abiding citizens to keep and bear magazines that have been considered appropriate for self-defense."

Attorneys general from Idaho, Alabama, Alaska, Arkansas, Florida, Georgia, Iowa, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nebraska, New Hampshire, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia, Wyoming, and the Arizona Legislature also joined the brief.

Meanwhile, the National Association for Gun Rights, the National Rifle Association, and the National Shooting Sports Foundation all filed their own similar but separate briefs with the Supreme Court on Tuesday as well. 

We visited with AG Knudsen at SHOT Show earlier this year and spoke to him about his feelings about the Second Amendment and his drive to defend it on a nationwide basis.
