Trump only cares about public service unions, he could care less about unions outside of government!!! I agree with him there should not be unions in government!! I thought that unionizing government workers was done with an EO why in the hell doesn’t he overturn that EO!!! He will cut government by 50% doing just that!!!
Technically he could.
But if you have been paying attention you might recall that Obama implemented the Dream Act with an EO.
Trump wrote an EO reversing that policy and the courts put a hold on that order and then said that ending it was unconstitutional.
The Dream act EO is just a few years old just imagine trying to reverse an EO over 60 years old.
