Obama Asks Cabinet For Gun Reform Proposals

Could include assault weapon ban

President Obama on Monday began the first serious push of his administration to attempt to reduce gun violence, directing Cabinet members to formulate a set of proposals that could include reinstating a ban on assault rifles.

The effort will be led by Vice President Biden, according to two people outside the government who have spoken to senior administration officials since Friday, when a gunman killed his mother and rampaged through Sandy Hook Elementary School in Newtown, Conn., killing 20 children, six adults and himself.
