The entire Northern Bering Sea is now off-limits to oil and gas leasing, under a presidential directive announced on Monday. President Joe Biden invoked his authority under a federal law to withdraw about 44 million acres of the Northern Bering Sea and other federal offshore areas from the Department of the Interior’s oil and gas

In response, Alaska’s new U.S. representative, Nick Begich III, called Biden a “son of a bitch” on social media and incorrectly suggested the action applied to Cook Inlet.

The decision adds to a closure Obama created. It’s not clear Trump can reverse it without an act of Congress. The oil and gas industry is not active in the area.
