President Barack Obama recently moved to indefinitely block oil and gas drilling on federally owned lands in the Arctic Ocean and Atlantic Ocean under a provision of the 1953 Outer Continental Shelf Lands Act. Canada took similar action. The act gives the president unilateral authority to withdraw parts of the Outer Continental Shelf from leasing, while leaving existing leases in place.

Trump could reverse the decision once he takes office. Read what Craig said in the media here:
