"I think that Mr. LaPierre's public handling of the aftermath of Newtown has been amply analyzed and discussed and has not been particularly helpful for his cause or the more important cause, which is reducing gun violence in America, and I think that's an assessment that is widely held," Carney said in an interview with MSNBC's "Andrea Mitchell Reports."
He also blasted Vice President Biden's suggestion that a shotgun would be as effective for protection as a so-called assault weapon like the one used in the Sandy Hook shooting.
"Have they lost their minds over at the White House?" LaPierre said. "You keep your advice, we'll keep our guns."
Carney said President Obama "believes we have to take steps to reduce gun violence — steps like closing loopholes in our background check system."
"I mean this is something that even the NRA, even Wayne Lapierre used to support," Carney said.
