newsweek.com – While both national parties argue in Congress over gun control bills, California has adopted sweeping legislation limiting semiautomatic rifles in response to the Orlando nightclub shooting massacre.

Governor Jerry Brown signed a package of six bills Friday that expand background checks for ammunition purchases; ban the sale of semiautomatic rifles with “bullet buttons” that allow for easy replacement of magazines; and restrict the loaning of guns without background checks to friends and family.

Meanwhile, national Democrats and Republicans continue a political battle over the proper response to the spate of mass shootings, with Republicans bending to possibly accept some gun control curbs but unwilling to agree with the extent of Democrats’ proposals. Frustrated Democrats resorted to a talking filibuster and a Congressional sit-in to force the issue in recent weeks, but Congress remains stalled.
