The NRA, the most powerful gun lobby, is prepared for battle, vowing to fight any proposed changes to current gun legislation to protect gun owners' rights.
"I think that's a real threat to their Second Amendment rights, and we intend to do all we can to protect them," NRA president David Keene said.
Gun control advocates hope that President Obama, fresh off his reelection victory, will be able to tap into the nation's outrage over the murder of 20 first graders at Sandy Hook Elementary School to get changes through Congress.
Spitzer said he is not sure whether that momentum will be enough.
"I think the likelihood that Congress will enact a sweeping set of gun control now is unlikely, but I think it's possible, because the conditions exist right now that are very similar to conditions that existed in the past when Congress did enact stronger gun laws," Spitzer said.
Biden is expected to make his recommendations Tuesday, and he has suggested that the president may be able to make some changes on his own using executive orders.
