The Senate Judiciary Committee next week will examine federal and state government reporting of criminal convictions to National Instant Criminal Background Check System, Chairman Chuck Grassley, R-Iowa, announced on Tuesday.

The panel will also analyze federal regulations governing so-called "bump stocks," gun attachments which can be attached to semi-automatic weapons to speed up firing speed.

The hearing's announcement comes hours after Senate Majority Whip John Cornyn, R-Texas, pledged to introduce a bill that would "incentivize" better reporting to the NICS, which is relied upon by gun sellers to filter out those who should not be allowed to purchase firearms.

Cornyn did not reveal the details of his proposal but said his legislation would offer "some collection of sticks and carrots" that "might be able to incentivize the state to cooperate more."

The shooter who killed 26 people in a Texas church on Sunday was able to purchase a gun despite a 2014 conviction for domestic assault. The Air Force acknowledged it failed to report the conviction.

Cornyn said federal regulations governing bump stocks need to be examined. The device was used by the Las Vegas shooter, who killed 58 people at a country music concert last month as he fired from the 32nd floor of his hotel room.

Cornyn said he wants Grassley to invite the Bureau of Alcohol, Tobacco, Firearms and Explosives "to explain why they reported, during the Obama administration, they did not think they had the authority to regulate these bump stocks."

Cornyn added, "I think we'll learn more in that hearing that we can then legislate from."
