FROM CNN WIRES:
Washington (CNN) - On one side were pegboard panels mounted with various assault rifles and semi-automatic weapons - including a Bushmaster similar to the one used in last month's Newtown school massacre.
Behind the stage stood police officers supporting a renewed ban on such firepower. One by one, victims of gun violence told their brief stories and expressed support for a new federal ban being proposed by Sen. Dianne Feinstein on some assault rifles and semi-automatic weapons.
Almost six weeks after the Connecticut shooting rampage that killed 20 first graders, Feinstein said she planned to introduce her measure later Thursday, with Reps. Carolyn McCarthy of New York and Ed Perlmutter of Colorado doing the same in the House.
Feinstein's proposal would upgrade an assault weapons ban that expired in 2004 and also outlaw ammunition magazines that hold more than 10 rounds.
She said the goal is to "dry up the supply of these weapons over time."
This morning on "Early Start," CNN's Paul Steinhauser looks at the details of Sen. Feinstein's plan and the public support for this type of assault weapons ban.
