The California Assembly has overwhelmingly passed a resolution opposing the Trump administration's push to renew oil drilling off the Pacific coast.
The Assembly on Thursday also asked U.S. Interior Secretary Ryan Zinke to remove California from the proposed leasing plan.
The 55-8 vote came on the same day as the only federal hearing in California on the plan.
Fishermen, environmentalists and other critics planned to protest at the California Capitol ahead of the hearing. Both the meeting and march in Sacramento come as two California commissions that oversee coastal lands and water pushed the Trump administration to leave the state out of its drilling plans.
The California State Lands Commission and California Coastal Commission say they will use their power to block pipelines that would get the oil on to land.
Assemblywoman Monique Limón, a Santa Monica Democrat who sought the resolution, cited previous offshore spills that have tarred the state's picturesque coastline.
Republicans Randy Voepel of Santee and Travis Allen of Huntington Beach say oil and gas can be can safely harvested. Allen, a GOP candidate for governor, says the move could help lower gasoline prices.
Interior Secretary Ryan Zinke wants to open nearly all U.S. coastlines to offshore oil and gas drilling.
The U.S. Bureau of Ocean Emergency Management has proposed six sales of drilling rights off the California coast and a seventh off Oregon and Washington between 2020 and 2023.
