Of course, and the examples you give are considered programmatic changes necessary in order for the Executive to implement the law.
The GAO found that in this instance that wasn't the case. They said the funds were withheld for policy reasons which is prohibited by the Impoundment Control Act.
We can say the ICA is bad, stupid or unconstitutional, but for now it's the law.
You are being obtuse and delusional. Our system of government with three co-equal branches does not require the President to kowtow to the policy decisions of previous Congresses, especially in Foreign Affairs.
Now about your assertion that constitutional laws must be obeyed. Not true. Its our duty as free citizens to disobey unconstitutional laws. If a law is unconstitutional, then multiple SCOTUS rulings have established it cannot be the law. Laws that are passed which are unconstitutional should not be obeyed, because they cannot be legally enforceable, as they are in contravention of the supreme law of the land and thus tyrannical. Its our duty to disobey them.
By the way, show me where Congress is permitted to stick its collective nose into Foreign Policy. . . especially the House of Representatives. The President is given the power to appoint ambassadors with the advice/consent of the Senate, and to receive ambassadors from foreign countries, the House can cut off funding in a budget, but thats it. Two hundred plus years of interpretation of that section of the Constitution, tradition, common law, and statutory law, has stated the President is empowered with Foreign Affairs, not Congress.
Where does it say that an annual budgetary foreign aid appropriation statute which requires budgeted funds be expended before a statutory September 30th end of the fiscal year or go unborrowed, somehow trumps the presidents constitutional control of foreign policy?
This is just more stuck pigs howling because theyve been stuck. The deep state swine are fearful theyre going to be turned into bacon. You should be familiar with it, you seem to squeal a lot on here.
