In United States government, the term describes the review, monitoring, and supervision of federal agencies, programs, activities, and policy implementation. Congress exercises this power primarily through its committee system. For example, a committee might hold hearings to investigate potential fraud within a government agency, ensuring funds are being used appropriately and policies are being carried out as intended.
This function is crucial for accountability and transparency within the executive branch. It helps to ensure that laws are being faithfully executed and that taxpayer money is spent wisely. Historically, significant events, such as the Watergate scandal, have highlighted the importance of robust mechanisms to prevent abuses of power and maintain public trust in government institutions.
