" executive power and issue an order halt "
What "executive power" to stop this.
This is a democracy, not an monarchy.
*ERGO: this is no "executive power(s)" possible in a republic/democracy, right??? So, there is no such precept as "balance of powers" - right? The elected chief executive - the president - is a powerless figurehead, right? The executive power of the president to "veto" a bill is a myth, right? Only inherited/appointed heads of "monarchies" have executive powers, that is, by "divine right endowed with (absolute) power", right? I have a different understanding of America's founding precepts for governance. My misunderstanding must be due to the proverbial generational gap. Perhaps, I need to confer with the ACLU...

That's quite a rant to say little. The President obviously has executive powers but he doesn't have executive powers such that for example he can tell Purpleland where your children can go to school. As I said, it's not a monarchy. The president can't just make people do things because that's what he wants. Would you like him to be able to dictate things like that to you? Maybe you should move to China.
