The move, an amendment to the National Defense Authorization Act — the must-pass funding bill for the military — was agreed to in a Democrat-heavy 225 to 205 vote. Introduced by U.S. Rep. Norma Torres, D-CA, the proposal would block President Trump’s nearly complete transfer of several weapons categories from export licensing controlled by the State Department to the more relaxed purview of the Commerce Department.

The three categories of the State Department’s United States Munitions List — those dealing with small arms including firearms, close assault weapons, combat shotguns and ammunition and ordnance — are set to transfer to the Commerce Control List, which, as previously reported, could benefit domestic gun and ammo makers looking to sell more overseas.
