Sen.-elect Elizabeth Warren is backing a bill reinstating a national assault weapons ban.

Warren said she grew up in a family that used guns for hunting and learned how to shoot in grade school.

But Warren said no one needs military-grade assault weapons to hunt, and no one needs what she called ``Rambo-style high capacity magazines'' to protect their family.

Warren said Congress also needs to close what she described as a loophole in the law that does not subject those purchasing guns at gun shows, online or person-to-person from a federal background check.

The newly elected Democrat said lawmakers must also look for other measures to curb the gun related violence.

Also, outgoing Sen. Scott Brown says he now supports a federal assault weapons ban.

Throughout his failed re-election campaign last year Brown said he opposed the ban, saying he believed states are the appropriate venue for weapons bans.  At the time, the Republican said he supported Massachusetts' assault weapons ban.

On Wednesday, Brown said he was changing his stance on the federal ban in light of the shooting deaths of 26 children and adults at a Connecticut elementary school last week, which he called beyond comprehension.
