Since Trump signs an executive order, it would be prudent for a "President" of the United States to know, and to be able to defend, his order....if he doesnt read what he signs, and blindly signs his name to what underlings have produced, he is guilty of being at least being ignorant of the situation and at most being complicit in the order(s) that have been deemed unconstitutional.

Wasn't the oath of the office to defend the Constitution? and not subvert it?

Trump has shown NO KNOWLEDGE of the Constitution, nor the ability to read......welcome to the White House to a person who knows little if anything about what is involved with maintaining a Constitutional Democracy.
