The White House is reportedly weighing gun-control measures that are broader and more comprehensive than bans on the sale of assault weapons and high-capacity ammunition clips.

Measures under consideration by a working group led by Vice President Joe BidenJoseph (Joe) Robinette BidenThe Hill's 12:30 Report Biden to decide on White House run at end of year Stormy Daniels’s 'View' is incorrect MORE include universal background checks for buyers, strengthened mental health examinations and stiffened penalties for carrying guns near schools or giving them to minors, sources told The Washington Post.

One source told the newspaper that the White House may try to rally support from gun retailers including Wal-Mart to work around the National Rifle Association.

Vice President Biden held the first meeting of the White House's gun-violence working group in December, following the mass shooting at Sandy Hook Elementary School in Newtown, Conn., that left 20 children dead.

The vice president said he would call on the law enforcement officials in the group to help in a legislative push against "everything from cop-killer bullets to type of weapons that should be off the street."

White House press secretary Jay Carney last month also outlined concrete recommendations the president was expecting from the working group.

Carney said that in addition to assault weapons and high-capacity ammunition clips bans, the White House would push a law that required background checks on all gun purchases, even those conducted at gun shows or over the Internet.

Carney added that the president would also call on Congress to "take action to improve coordination between the federal government and state and local law enforcement to keep illegal guns out of the hands of criminals."

Members of the 113th Congress introduced 10 bills on Thursday relating to gun violence, most of which came from Democrats seeking new restrictions on gun ownership.

The flurry of legislative proposals shows that members are likely to push the issue in the wake of the Newtown shooting.
