Final answer:
Congress exercises oversight over the bureaucracy through funding control, confirmation process, and hearings.
Step-by-step explanation:
Congress exercises oversight over the bureaucracy in several ways. One way is through its power to control funding. Congress can allocate or withhold funds to hold the bureaucracy accountable for its actions. Another way is through the confirmation process for presidential appointments. Congress must confirm the heads of cabinet departments and many independent executive agencies, giving them the opportunity to question and scrutinize these key officials.
Additionally, Congress holds hearings where leaders of the bureaucracies are questioned about their activities and budgets. These hearings allow for fact-finding and can become animated if there has been a significant blunder. Through these oversight mechanisms, Congress ensures that the bureaucracy is accountable and transparent.
