California officials on Thursday said the state has appealed a federal judge’s decision to strike down its three-decade-old ban on assault-style weapons, saying the law is needed to prevent gun deaths. The appeal challenges last week’s ruling from U.S. District Judge Roger Benitez of San Diego that the law illegally infringes upon the U.S. Constitution’s Second Amendment, which guarantees the right of citizens to bear arms. …Gov. Gavin Newsom and Attorney General Rob Bonta, both Democrats, told a news conference outside a San Francisco hospital they were confident the decision was flawed and would eventually be overturned.
