Instead, LaPierre reiterated the group's support for putting police officers in every school.
"If it's crazy to call for putting police and armed security in our schools to protect our children, then call me crazy," LaPierre said on NBC's "Meet the Press." ''I think the American people think it's crazy not to do it. It's the one thing that would keep people safe."
Sen. Joe Lieberman, a Connecticut independent, said he found the NRA's statements in recent days to be "really disheartening." Still, he said he agrees with some of the points the group has made about the causes behind violence in America.
"But it's obviously also true that the easy availability of guns, including military-style assault weapons, is a contributing factor, and you can't keep that off the table. I had hoped they'd come to the table and say, everything is on the table," Lieberman said.
Sen. Chuck Schumer, D-N.Y., said LaPierre was "so extreme and so tone deaf" that he was making it easier to pass gun legislation.
"Look, he blames everything but guns: movies, the media, President Obama, gun-free school zones, you name it. And the video games, he blames them," Schumer said.
Lieberman said the NRA's stand on new gun rules means passing legislation next year won't happen easily.
"It's going to be a battle. But the president, I think, and vice president, are really ready to lead the fight," he said.
