The President and the Attorney General, subject to the President’s supervision and control, shall provide authoritative interpretations of law for the executive branch. The President and the Attorney General’s opinions on questions of law are controlling on all employees in the conduct of their official duties. No employee of the executive branch acting in their official capacity may advance an interpretation of the law as the position of the United States that contravenes the President or the Attorney General’s opinion on a matter of law, including but not limited to the issuance of regulations, guidance, and positions advanced in litigation, unless authorized to do so by the President or in writing by the Attorney General.
