In announcing his gun control package, Obama also signed executive actions that call for tougher enforcement of existing laws and require federal agencies to provide data for background checks.
New York state recently enacted a series of new gun regulations, the nation's first since the Newtown shootings. Ten other states are reviewing some form of related action.
The issue is among the most politically divisive in the country, as demonstrated by the decision by Reed Exhibitions to postpone the nine-day Eastern Sport and Outdoor Show scheduled to start February 2 in Harrisburg.
On Tuesday, the NRA withdrew its support for the show due to the decision by organizers to ban modern sporting rifles from exhibition.
"We had called on Reed Exhibitions to reconsider their decision; unfortunately they have steadfastly refused to do so," an NRA statement said. "As a result, the NRA will not be participating in the upcoming show in Harrisburg or in any other shows hosted by Reed Exhibitions that maintain this policy."
In announcing Thursday that the show was off, a Reed Exhibitions official said the intent of excluding "certain products" was to focus on hunting and fishing traditions of the event.
"It has become very clear to us after speaking with our customers that the event could not be held because the atmosphere of this year's show would not be conducive to an event that is designed to provide family enjoyment," said Chet Burchett, the company's president for the Americas.
"It is unfortunate that in the current emotionally charged atmosphere this celebratory event has become overshadowed by a decision that directly affected a small percentage of more than 1,000 exhibits showcasing products and services for those interested in hunting and fishing," he added.
