Executive privilege refers to the president's contention that certain communications or information related to their role as a chief executive should be kept confidential. It is the president's claim of privilege to withhold certain documents, conversations, or other materials from being disclosed to Congress, the judiciary, or the public.
Executive privilege is based on constitutional assertions of the president's power and authority. It is rooted in the idea that the president requires a certain degree of confidentiality and secrecy to effectively carry out their duties and make informed decisions. However, it is imperative to note that executive privilege is not explicitly mentioned in the United States Constitution. However, it has been recognized and upheld by the courts based on the separation of powers and the president's need for candid advice and deliberation.
Executive privilege is not related to the president's ability to use Air Force One on nonmilitary excursions or their constitutional authority over the other branches of government. It specifically pertains to the confidentiality of communications and information.
