The NRA-ILA issued an alert on Saturday after the story broke about the proposal to include 4.2 million Social Security recipients in the NICS database as prohibited persons. This proposal from the Social Security Administration has been traced back to a Presidential Memorandum issued in 2013. That memorandum, issued post-Newtown, ordered Federal agencies to improve the availability of relevant records for inclusion into the NICS database.
The alert does not explain why it took the SSA over two and a half years to come forward with this proposal. Moreover, the alert notes that other Federal agencies were named in the memorandum and might be expected to add even more names to the prohibited list.
There are links in the alert to communicate with your legislators.
