The National Rifle Association is warning that the United Nations Arms Trade Treaty set to take effect on Dec. 24 could lead to increased gun control if President Obama implements it via executive order.

“We are worried about an end-run around Congress,” NRA spokeswoman Catherine Mortensen told The Blaze. “Barack Obama or a future anti-gun president could use [the treaty] and international norms compliance to rationalize enacting gun control politics through executive actions, especially in the import and export realms.”
