Under this EO he could even choose to “interpret the law” such that it was illegal for the Marshal’s service to arrest executive branch officials without explicit Presidential permission (and this flows naturally from the same version of unitary executive theory as this EOs rule on legal interpration itself relies on), and it would not only be a violation of this order for them to carry out the arrest, but it would be a violation of the order for anyone in the executive branch to disagree that that was the law.
