Trump ended rule to block mentally ill from getting guns

The action was one of his earliest as president.

In November, President Trump cited mental health as the reason for the Sutherland Springs, Texas, church shooting that left 26 people dead.

According to estimates from the previous administration, had the Obama-era regulation gone into effect, an estimated 75,000 individuals with mental illnesses would have been added to the database. These individuals would have been notified by the Social Security Administration of their possible restrictions to buy firearms but would have the opportunity go through an appeal process.

Although the rule was made effective days before Trump took office in January 2017, compliance was not required until December 2017.

The White House has not responded to ABC News' request for comment.
