Congress on Wednesday sent President Donald Trump legislation blocking an Obama-era rule designed to keep guns out of the hands of certain mentally disabled people. The Senate backed the resolution on a vote of 57-43. The Obama-era rule would have prevented an estimated 75,000 people with mental disorders from being able to purchase a firearm. It was crafted as part of efforts to strengthen the federal background check system in the wake of the 2012 massacre at Sandy Hook Elementary School in Newtown, Connecticut. The rule required the Social Security Administration to send in the names of beneficiaries with mental impairments who also have a third party manage their benefits.The regulation was removed through the Congressional Review Act, which allows a simple majority of both chambers to pass a joint resolution of disapproval that must then be signed by the President.
