Vice President Joe Biden is finalizing a set of recommendations to curb gun violence, which he's expected to hand over to President Barack Obama Tuesday.
Some lawmakers say last month's shooting in a Connecticut elementary school transformed the country, and Americans are ready for stricter gun laws. The National Rifle Association predicted Sunday that Congress is likely to block any new laws that would ban assault weapons.
As this plays out, schools are grappling with the issue of safety. The NRA's response to the shooting was that all schools should have armed guards.
