Legislation can not be enacted solely by the POTUS, he has no authority for this. It lies in congress.
And there will be court cases
Ol’ joshee boy ought not be surprised. He ought to count on it going to court. But, knowing the lyin’ king and his minions, they’ll push their desires forward court or no court. It’s the old forgiveness permission thing.
It is preposterous on the face of it. It simply CANNOT be “legislation” if it doesn’t originate in the legislature. Impeach! Imprison!
