>It is not debateable at all, the President has to ask Congress to rescind appropriated funds if the President doesn’t want to spend the money allocated by Congress. If Congress chooses not to rescind the allocated funds, then the president must spend the money.

What people don't understand is that the President is essentially an Administrator (Executer of the laws passed by Congress), not a Decider.

The problem now is that Congress will not impeach or convict him for breaking the law.
