It then provides analysis of the Senate amendments offered in the 114th Congress that would have addressed issues regarding expanding federal background check requirements to private non-licensed gun sellers in public places, allowing the Attorney General power to stop the sale of firearms or explosives to a person deemed "a dangerous terrorist", revising and codifying rules regarding people with mental health conditions acquiring firearms, and improving computer systems and the availability of information on persons not authorized to possess a firearm . It also tracks the status of gun control related appropriations for the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Federal Bureau of Investigation National Instant Criminal Background Check System (NICS) Section, National Criminal History Improvement Program (NCHIP), and NICS Amendments Record Improvement Program (NARIP).
