Citing recent mass shootings in Orange, Boulder, Colo., and the Atlanta area, state lawmakers on Tuesday advanced a proposal for a new tax on the sale of guns and ammunition in California to boost funding for violence prevention programs.

The legislation by Assemblyman Marc Levine (D-San Rafael) would place a $25 excise tax on retailers for the sale of each new gun and an as-yet-undetermined levy on ammo sales to raise millions of dollars to fund the efforts.

“Gun violence will not end on its own,” Levine told the Assembly Public Safety Committee during a hearing Tuesday. “We must take responsible action to end the public health crisis that is gun violence in our state, in our nation.”

The panel voted 5 to 2 along party lines to approve the legislation, which still needs approval from the full Assembly.
