The Hughes amendment to the Firearms Owners Protection Act (FOPA) closed the machine gun registry in 1986. The problem is that there is now video available of the vote to add the Hughes amendment that clearly shows that the motion to add it failed in committee. However it was sent to the Senate with that amendment attached anyway after the house approved the FOPA without the Hughes amendment. Once passed in the Senate, President Regan signed it into law.
By all rights the Hughes amendment should never have been included and signed into law, yet it now on the books. Please press Congress to repeal the Hughes amendment, especially since it was never passed legally to begin with.
