SACRAMENTO – Senator Anthony J. Portantino (D – Burbank) announced his support of Governor Newsom’s proposal for a 28th Amendment to the U.S. Constitution that would guarantee common sense gun safety measures and protections broadly supported by the American public and gun owners. The proposal includes universal background checks, raising the firearm purchase age to 21, instituting a reasonable waiting period for all gun purchases, and banning the purchase of assault rifles for civilians. Senator Portantino will co-author the Senate Resolution that will begin the constitutional amendment process.
