Executive privilege refers to the power of the President of the United States to withhold information from other branches of government, particularly Congress, and the judiciary. This privilege is based on the need for confidentiality in the executive branch, allowing presidents to communicate freely with advisors without the fear of public disclosure. It often comes into play during legal disputes or congressional investigations. However, the scope and limits of executive privilege are contentious issues, as it raises questions about transparency, accountability, and the balance of power among the branches of government, especially during times of crisis.
