The current crop of progressive (socialist/tyrannical) democrats in office flatly ignore the law of the land -- the U.S. Constitution.
They refuse to recognize that all federal funding MUST originate in the House of Representatives.
The President may propose a budget, but it is up to the House to determine what will be funded. When the President and the Senate ignore the will of the House (an hence the will of the People), they do so at their own peril.
The Supreme court, if they are wise, will stay clear of these political conflicts. Sadly, the Roberts court strayed from the Constitution and ruled Obamacare a tax.
Rules are made to be broken, and bad rules (law) must be repealed!
History shows that bad laws can be overturned, and that the People, when motivated, will prevail -- either at the soap box, ballot box, or bullet box.
That is why tyrants fear a free people empowered to gather in peaceful assembly (as in the closing of National parks and places), a People who publicly seek redress of wrongs by their government, and who are armed to defend themselves from the unlawful power of the State.
