You know also: while Congress does usually
retain the right to overrule a Presidential determination about dissolving an agency or a department, nevertheless, Congress does have the authority to delegate such governmental organization decisions to the President.
The delegation laws are a matter of historical fact and have gotten judicial approval (with some provisos).
So, let’s say that Congress agrees to do so for Trump. And Trump thereby elects to dissolve the Dept of Education. And maybe to demonstrate Republicans good faith with the voters, Congress decides not to overrule Trump.
Violá. No more Department of Education.
Alternatively, the President declares that the existence of the Dept of Education violates the Constitution. And pursuant to his Oath of Office, he orders it dissolved. A court case would ensue. That’s for certain.
So I’ll ask again:
What enumerated power granted by the Constitution authorizes the existence of the U.S. Department of Education?
