I disagree here. Congress makes the laws (to include appropriations bills), and the executive “executes” those laws. The bureaucracy is responsible to execute the budget as provided by the Congress. There is no sworn requirement of the bureaucracy to “monitor” the public interest. That is not their role. That is the role of the Congress. There are mechanisms for the bureaucracy to revise and petition the Congress to make changes if they believe certain actions are counter to what they believe, however the ultimate responsibility lies with Congress.
