Attorney General Jeff Sessions is ordering a far-ranging review of the FBI database containing information for use in background checks on prospective gun buyers, according to the Associated Press.
The move comes after the Air Force acknowledged that a man who killed more than two dozen people in a south Texas church should have had his name and domestic violence conviction submitted to the database. That might have prevented him from buying guns.
In a memo, Sessions directed the FBI and ATF to determine if other government agencies are failing to report information to the National Instant Criminal Background Check System. He also wants a report detailing the number of times the agencies investigate people for lying on their gun-purchase applications.
The Pentagon's inspector general is separately reviewing the case of the Texas gunman.
