US President Donald Trump has signed a measure nixing a regulation aimed at keeping guns out of the hands of some severely mentally ill people.
The regulation, which was repealed on Tuesday, was part of a series of efforts taken by the Obama administration to try and curb gun violence after other efforts failed to advance in Congress, CNN reported.
The ban was promoted by Obama as part of his plan to increase control over access to firearms following the Newtown Sandy Hook school massacre in 2012, when 20 children and six teachers were gunned down.
The regulation, estimated to affect some 75,000 people, required the Social Security Administration to report to the federal government the names of people receiving disability benefits because of mental health problems, in order to block them from buying arms.
Tuesday's decision was cheered by the National Rifle Association (NRA), the principal group promoting the right of individual citizens to bear arms.
