I made the distinction in the post you responded to, where I referred to “actual laws” being different than EO’s. But EO’s carry “the force of law” and are therefore very very similar in power and authority.
An EO is a declaration by the president which has the force of law, usually based on existing statutory powers, and requiring no action by the Congress. They are numbered consecutively, so executive orders may be referenced by their assigned number, or their topic. A sitting U.S. President may overturn an existing executive order by issuing another executive order to that effect.
Maybe my point wasn’t clear. Why would a President issue a formal order to tell HIMSELF what to do (or not do)?
