In 1969, a public debate between President Nixon and Congress took place during the legislative passage of the National Environmental Policy Act and centered on two very different and competing conceptions of how presidential advice should be organized in the Executive Office of the President. It focused on the proposed establishment of the Council on Environmental Quality. The outcome of the ensuing battle represented a complete victory for congressional interests against the expressed wishes of the president. The nature of the debate has been overlooked in the literature on the presidency, but it highlights fundamental issues about agency design and presidential control of the institutional presidency. It also highlights broader concerns about the degree of congressional involvement in shaping the Executive Office of the President.
