Newsom takes aim at nationwide gun safety with proposed constitutional amendment

California boasts some of the toughest gun safety laws in the nation, and they would become the blueprint for all 50 states if Gov. Gavin Newsom has anything to say about it.

On Thursday, Newsom proposed a constitutional amendment to enshrine gun safety measures nationally. His proposed 28^th Amendment to the U.S. Constitution includes four gun safety measures that are already part of California law: universal background checks, raising the firearm purchase age to 21, instituting a firearm purchase waiting period and barring the civilian purchase of assault weapons.
