The Trump administration has proposed allowing offshore oil and gas drilling in nearly all of the United States’ coastal waters. The reversal of the Obama-era restrictions would open more than a billion acres of water along the Eastern Seaboard and in the Arctic and allow oil companies to drill off the coast of California for the first time in decades. The proposal faces opposition from environmental groups and the governors of New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, California, Oregon, Washington and Florida.
