Many politicians, primarily but not exclusively of the Progressive-Democratic Party, when they decry the actions of President Donald Trump (R) loudly declaim that whatever it is that he’s doing is “unconstitutional.”
It’s instructive that these worthies usually omit to cite the clause of our Constitution that’s supposedly being violated, but when they do cite something, they center their claim on the 10th Amendment.
Here is what that Amendment says:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
Article I, Section 10, lays out specific powers prohibited to the States:
No State shall enter into any Treaty, Alliance, or Confederation; grant Letters of Marque and Reprisal; coin Money; emit Bills of Credit; make any Thing but gold and silver Coin a Tender in Payment of Debts; pass any Bill of Attainder, ex post facto Law, or Law impairing the Obligation of Contracts, or grant any Title of Nobility.
No State shall, without the Consent of the Congress, lay any Imposts or Duties on Imports or Exports, except what may be absolutely necessary for executing it’s inspection Laws: and the net Produce of all Duties and Imposts, laid by any State on Imports or Exports, shall be for the Use of the Treasury of the United States; and all such Laws shall be subject to the Revision and Controul of the Congress.
No State shall, without the Consent of Congress, lay any duty of Tonnage, keep Troops, or Ships of War in time of Peace, enter into any Agreement or Compact with another State, or with a foreign Power, or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay.
Included in the powers not delegated is this one from Article II, Section 3:
…he shall take Care that the Laws be faithfully executed….
Here is what the Supremacy Clause of our Constitution says, from Article VI:
This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.
There is nothing in the supreme Law of the Land that has been delegated to the States or to the people. That supremacy has been retained by the Federal government, and that supremacy includes actions of Federal law enforcement agencies and their personnel in the course of their enforcement of Federal laws in Progressive-Democrat-run “sanctuary” jurisdictions; the latter’s protestations to the contrary are irrelevant.
No part of a President’s authority or obligation to enforce the Laws are reserved to the States. Nor does the 10th Amendment’s delegations include any State-level authority to block or otherwise interfere with Federal law enforcement actions.
