2013: Special Prosecutor Leon Jaworski’s confidential Watergate files surfaced at the National Archives, which contain details of a series of secret meetings that prosecutors had held with trial judge John Sirica, including agreement enabling him to name himself as trial judge. Archival documents also show prosecutor’s facilitated John Dean’s temporary sentencing to improve his witness credibility, kept exculpatory evidence from defense counsel, and made secret, but erroneous, allegations regarding Nixon’s own Watergate conduct.
2015: Associate Special Prosecutor James Vorenberg’s handwritten staff meeting notes surfaced at Harvard’s law library, confirming much of the same improper prosecutorial conduct.
