what has the supreme court said about executive privilege
Executive privilege Executive privilege is the power of the President of the United States and other members of the executive branch of the United States Government to resist certain subpoenas and other interventions by the legislative and judicial branches of government in pursuit of information or personnel relating to the executive. The power of Congress or the federal courts to obtain such information is not mentioned explicitly in the United States Constitution, nor is there any explicit mention in the Constitution of an executive privilege to resist such requests from Congress or courts.[1] The Supreme Court of the United States has ruled this privilege may qualify as an element of the separation of powers doctrine, derived from the supremacy of the executive branch in its own area of Constitutional activity.[2]
