The U.S. government’s most significant prosecution of an American media outlet prior to the Pentagon Papers fell through during World War II when a grand jury refused to indict the Chicago Tribune in 1942 for an article stating the U.S. Navy had advance knowledge of Japanese plans to attack Midway Island in June of that year.

Documents posted today by the George Washington University-based National Security Archive detail FBI, Justice Department, and Navy efforts to charge the Tribune with damaging national security by indirectly alluding to U.S. penetration of Japan’s naval codes – one of the most sensitive secrets of the day.
