I wish that Executive Orders didn’t even exist, at least not as they are practiced now.
Previously, an Executive Order was simply an instruction by the President to his cabinet on following the congressional laws.
Now, these are laws that are passed by the Executive Branch. And they are deemed legal as long as they are not unconstitutional.
The US Constitution, however, only calls for the Executive Branch to faithfully execute the law (as Congress writes them). See Article 2, Section 3, Clause 5 of the US Constitution. Find anywhere in there that the president has the right to write law, even if it is deemed constitutional.
The president should only need to remind his cabinet to follow the law as congress has written it. If congress doesn’t like it, they need to change it.
