Press secretary Jay Carney said the president would back Sen. Dianne Feinstein (D-Calif.) when she introduces legislation at the opening of the next Congress to ban certain assault weapons in the United States.

Carney said the president would also support other gun-control efforts, including legislation to close the “gun show loophole” on background checks and prevent the sale of high-capacity ammunition clips.

The president has reached out to lawmakers who have expressed a new willingness to consider gun restrictions in the wake of Friday’s mass shooting in Newtown, Conn., that claimed the lives of 27 people, including 20 children. Carney said Obama has been “heartened” by the willingness to consider such measures from Democrats who have been strong supporters of gun rights.
