On June 17, 1972, several people broke into the Democratic National Committee Headquarters; they were discovered by an on-site guard and were arrested by local police. Subsequent investigations by the FBI, Congress, and the media showed that these intruders were connected to the campaign staff of President Richard Nixon. The White House under Nixon worked to cover-up this connection, and subsequent revelations led to articles of impeachment being drawn up against Nixon and his subsequent resignation in 1974. These files, released many years ago, document the FBI’s investigation into the break-in and related issues between 1972 and 1979.
