In a series of memos Monday, President Donald Trump said he could continue invoking the Defense Production Act to push through oil, natural gas, and coal projects.

The administration last month cited the 1950 law enacted during the Korean War to restart a California oil pipeline that caused a massive oil spill near Santa Barbara in 2015. The law allows the president to identify specific goods as "critical and strategic,” with the administration arguing it gives the president the ability to supersede state laws.

The move to restart the pipeline came amid rising global fuel prices due to the administration’s decision to join Israel in attacking Iran. Trump’s memo this week stated that “ensuring resilient domestic petroleum production, refining, and logistics capacity is central to United States defense readiness.” Trump issued similar memos for coal and natural gas.

The U.S. is already producing more oil than any country in history, with last year’s production setting another new record. That production has not stopped global oil prices from spiking due to the closure of the Strait of Hormuz, a critical chokepoint that about a fifth of the world’s oil supply must pass through.
