The Trump administration, inviting a political backlash from coastal state leaders, on Thursday proposed to open for exploration the largest expanse of the nation's offshore oil and natural gas reserves ever offered to global energy companies, including waters off the coast of California.

Interior Secretary Ryan Zinke said the draft five-year leasing plan would commit 90 percent of the nation's offshore reserves to leasing, including areas off all three regions of the California coast that have been off limits to oil and gas exploration since the Reagan administration.

The draft plan, now subject to review and debate, would allow the first new federal lease sales off the California coast since 1984. It sparked immediate fury from Democratic leaders in the state.

"The American people deserve smart, strong action to keep our communities healthy, clean and safe. Yet the Trump administration is racing forward with its increasingly brazen attempts to loot our environment and our planet," House Democratic leader Nancy Pelosi said in a statement. "Americans from coast to coast will make their voices heard to oppose this blatant corporate giveaway."
