The Senate has voted again to kill a bill requiring background checks of most buyers at gun shows.

Senators rejected the bill on Tuesday, but then voted to reconsider it a day later. Without discussion, they killed the bill on a 19-21 vote on Wednesday.

The bill's sponsor, Sen. Henry Marsh, had said there may be attempts to water down the bill to make it more likely to pass. But on Wednesday, he asked for a vote on the original bill.

Marsh's bill would have closed the so-called "gun-show loophole," where private sellers at the public events are not required to conduct the background checks that licensed dealers must perform.

It would have required background checks on everyone except those who already have a permit to carry a concealed weapon or those purchasing antique guns.
