This week the US Air Force (USAF) admitted it had failed to provide NICS with information regarding a domestic violence conviction of their former officer Devin Kelley.
As a result Kelley was able to purchase the rifle, which he is accused of using to kill at least 26 people in Sutherland Springs, Texas.
According to USA Today the USAF has said it is investigating the failure to provide this information.
In a memo to officials in the FBI and the Bureau of Alcohol, Tobacco, Firearms, and Explosives, issued Wednesday, the Attorney General Jeff Sessions announced plans to review NICS to prevent this kind of oversight from recurring.
In a statement, Sessions said;
[NICS] is critical for us to be able to keep guns out of the hands of those that are prohibited from owning them...
The recent shooting in Sutherland Springs, Texas revealed that relevant information may not be getting reported to the National Instant Criminal Background Check System - this is alarming and it is unacceptable.
