A fundamental objective of congressional oversight is to hold executive officials accountable for the implementation of delegated authority. This objective is especially important given the huge expansion of executive influence in the modern era. If the Founding Fathers returned to observe their handiwork, they would likely be surprised by such developments as the creation of a "presidential branch" of government (the Office of Management and Budget, the National Security Council, and the like) and the establishment of so many federal departments and agencies.
