Executive privilege (EP) as a political tool has created a grey area of constitutional power between the legislative and executive branches. By focusing on the post-WWII political usage of executive privilege, this research utilizes a social learning perspective to examine the power dynamics between Congress and the president when it comes to government secrecy and public information. Social learning provides the framework to understand how the Cold War's creation of the modern American security state led to a paradigm shift in the executive branch. This shift altered the politics of the presidency and impacted relations with Congress through extensive use of EP and denial of congressional requests for information. When viewed through a social learning lens, the institutional politics surrounding the development of the Freedom of Information Act is intricately entwined with EP as a political power struggle of action-reaction between the executive and legislative branches. Using extensive archival research, this historical analysis examines the politics surrounding the modern use of executive privilege from Truman through Nixon as an action-reaction of checks on power from the president and Congress, where each learns and responds based on the others previous actions. The use of executive privilege led to the Freedom of Information Act showing how policy can serve as a congressional check on executive power, and how the politics surrounding this issue influence contemporary politics.
