The Air Force admitted Monday that it failed to report the conviction to the FBI's national database of criminal records that is used for background checks.
Federal law prohibits individuals convicted of a misdemeanor crime involving domestic violence from owning firearms. Purchasers are required to answer a series of questions created to determine whether they are legally eligible to buy and possess firearms. "For example, a person convicted of misdemeanor assault against his or her spouse would be prohibited from receiving or possessing firearms", according to a provision in the Federal Gun Act of 1968.
"We need to better understand why our existing laws didn't work in this instance and that is what my proposed legislation would do after analyzing the problem we will try to ensure that everyone is complying with the law", added Cornyn.
"Bad Conduct Discharge" and "Dishonorable Discharge" classifications are the only two types of separations where a military member is court martialed", according to Bennett Gore, a former member of the Army's Judge Advocate General Corps. The Pentagon has also requested that its own inspector general review the handling of Kelley's records, along with the Air Force, as well as its reporting practices more broadly.
Sen. John McCain (R-AZ), the chair of the Senate Armed Services Committee, said on Monday night that his committee will conduct oversight over the Defense Department's investigation into the Air Force's failure to report the Texas shooter's criminal history to the FBI.
Robert Mugabe fires vice president as Zimbabwe's succession battle intensifies
President Mugabe fired Mnangagwa, who allegedly led another faction, citing disloyalty, deceitfulness and other issues. Mr Mugabe will likely face a weakened and fractured opposition when he contests next year's elections.
A sixth discharge, known as "Other Discharge" typically happens before a military member finishes basic training.
In 2007, Virginia Tech student Seung-Hui Cho shot and killed 32 people and himself at his college campus.
"There are thousands and thousands of people in this country who have criminal records, who are seriously mentally ill, who shouldn't be able to buy guns and whose records are not on that system", said Murphy (D-Connecticut).
All four purchases were never flagged by the federal background check system.
The federal background check system is also notoriously underfunded, understaffed, and underresourced, allowing red flags to slip through. But these three days are a maximum for the government - and sometimes, the three days lapse without the Federal Bureau of Investigation completing its check, and a buyer can, at that point, purchase a gun without the completed check.
"It would also underscore the weakness of not having universal background checks", he said. But licensed dealers at gun shows still have to carry out a background check. In other words, the gun show doesn't create a loophole; the private seller does.
