(CNN) - Senate Majority Leader Harry Reid said Thursday he'll set aside proposed gun legislation without a final vote following the defeat a day earlier of major provisions sought by President Barack Obama and Democrats in the aftermath of the Newtown school massacre.
"(Obama) and I agreed that the best way to keep working towards passing a background check bill is to hit pause, and freeze the background check bill where it is," he said on the Senate floor. "This will allow senators to keep negotiating."
A Senate Democratic leadership aide said Reid can bring up the package of gun proposals again if circumstances change and he believes he has the votes for key provisions to pass, particularly a measure to expand background checks on gun buyers.
"We're gonna have time to work on what people want to do before we come back to this," Reid said, adding that this option allows them to return to the bill without returning to square one. "It will only be a matter of time."
"The stand of the Republicans is not sustainable," he said. "The question is how long they're going to stand firm–but it's not sustainable."
In a major defeat for supporters of tougher gun laws, the Senate on Wednesday defeated a compromise plan to expand background checks on firearms sales as well as a proposal to ban some semi-automatic firearms modeled after military assault weapons.
