Biden: NRA meeting was 'productive'

Capping off a week of meetings with stakeholders in the debate over gun control, Vice President Joe Biden called a session with the National Rifle Association 'productive' despite the group's public complaints yesterday. 

"I thought we had a very straightforward, productive meeting," Biden said of yesterday's closed-door session with pro-gun groups.

The NRA charged in a statement yesterday that the Obama administration has "an agenda to attack the Second Amendment."

Vice President Joe Biden will present his task force's gun policy recommendations Thursday – among them, most likely, to reinstate the Assault Weapons Ban. NBC's Peter Alexander reports.

But Biden said that the variety of gun owners' organizations that met at the White House yesterday did not all share the NRA's opinions on the causes of and potential solutions for mass gun violence. 

“There was actually a difference among them as well,” he said. “There was not a uniform view.”

Biden invoked a common metaphor about firearms to describe the challenges facing foes of gun violence. 

"We know there's no silver bullet" for stopping mass shootings, he said during a meeting with video game industry representatives.

The vice president has said he wants his task force to present recommendations to the president by next week. 

"I'm shooting for Tuesday," he said. "I hope we get it done by then."
