"It's a complex problem that requires more than one solution," White House spokesman Jay Carney said Tuesday. "It calls for not only re-examining our gun laws and how well we enforce them, but also for engaging mental health professionals, law enforcement officials, educators, parents and communities to find those solutions."
Still, much of the immediate focus after the shooting is on gun control, an issue that has been dormant in Washington for years. Obama expended little political capital on gun issues during his first term, despite several mass shootings, including a movie theater attack in Aurora, Colo., in the midst of this year's presidential campaign.

The White House has begun to signal that Obama may be more proactive on gun issues following the murders of the elementary school youngsters, ages 6 and 7.
Carney said Obama was "actively supportive" of legislation to reinstate a ban on assault-style weapons that expired in 2004. The president long has supported a ban, but exerted little effort to get it passed during his first term. Obama also would support closing a gun show loophole allowing people to buy arms from private dealers without background checks and would be interested in legislation limiting high-capacity ammunition magazines, Carney said.
The policy process will include input from the departments of Justice, Education, and Health and Human Services. The heads of those agencies met with Obama at the White House on Monday.
The Department of Homeland Security is also expected to play a key role.
