Reaching back in history:
President Harry Truman’s April 8, 1952 Executive Order 10340 authorized Secretary of Commerce Charles Sawyer to seize the U.S. steel mills in advance of a strike that was to have begun the next day.
Owners of the steel companies took the matter to the federal courts, obtaining an injunction against Truman’s Executive Order. Ultimately, the Supreme Court ruled against the president on June 2, 1952 in the case Youngstown Sheet and Tube Company v Sawyer.
The “law of the land” CAN be overturned, even when there seems to be a fairly firm basis for its issuance.
The EO so recently issued by the Current Occupant is on much less firm legal grounds. The governors of the several States, and members of Congress, all have legal standing to bring this to the attention of the Federal courts.
It just takes the testicular fortitude to commence action.
That eliminates the Republican Party.
