The president is calling for the measures in response to the December 14 school shooting in Newtown, Conn., that killed 20 students and six adults.
The president also will push for other steps that could include executive actions that don't require congressional approval, according to White House press secretary Jay Carney.
The announcement will set off a battle with Congress, according to the Washington Post. The president's agenda has at best lukewarm support from his party's leaders and puts him at odds with Democratic centrists.
Also, CNN reported that the National Rifle Association has experience a large surge in membership growth since the new calls for gun control began in December.
Approximately 250,000 people have joined the organization's existing 4.25 million members, according to CNN.com.
