Arnold Schwarzenegger and Jane Fonda joined California Gov. Gavin Newsom and environmental advocates in Los Angeles on Friday to launch a campaign to keep a 2022 law banning new oil and gas wells near homes, schools and hospitals. The law bans new wells within 3,200 feet (975 meters) of certain community sites, and proponents say it will protect residents from the health impacts of pollution. It hasn't taken effect after the oil industry qualified a referendum to ask voters to overturn it in November.
