Uh, we need a Constitutional Amendment...or a USSC to rule against stare decisis.
This is not a change the Executive can make.
And it would be a precedent that no lover of liberty would want to see.
It’s just good that he is announcing it as an option. Of course this is a constitutional amendment situation. I think it could be very simple. All who are born on American soil to legal citizens and residents. No tourists or students or illegals. Perfect.
