The National Rifle Association is going after Senator Heidi Heitkamp (D-ND) after she announced she will vote no in opposition to the Supreme Court nomination of Judge Brett Kavanaugh.

"Today, Heidi Heitkamp put partisan politics above the rights of law-abiding North Dakota gun owners. Right now, the U.S. Supreme Court is split 4-4 on the basic right to keep a firearm in the home for self-defense. Therefore, a vote against confirming Judge Kavanaugh to the Supreme Court is a vote against the fundamental right to self-defense,” the NRA released in a statement.
