It’s BS and doesn’t mean a thing. One branch of govt. cannot usurp powers belonging to another branch. It’s the checks and balances thing. If I were Pres. Trump I’d get a judge to OVERRULE congress and give them a taste of their own medicine.
“One branch of govt. cannot usurp powers belonging to another branch”
Correct. Which branch raises an Army and a Navy, makes the rules to administer them, and declares war?
