“In issuing and implementing Executive Order 13921, the Trump administration made it clear that it was intended to reduce the burdens on commercial fishing operations, and it indisputably shifts the cost of planning for such operations to taxpayers and reduces regulatory review of proposed projects despite the extensive harm to fish and the marine environment,” the letter states. “Your administration has already taken many actions to stay, suspend, or reverse Trump administration decisions that jeopardize wildlife and the environment. We commend you on those efforts and urge you also to revoke Executive Order 13921 to end this damaging policy in order to protect countless fish, other marine animals including birds, the sensitive marine environment, and potentially even human health from significant harm.”
