“The U.S. government attempted to aggressively prosecute a journalist who revealed early in World War II that American intelligence agencies had cracked the Japanese military’s secret code language. According to the Wall Street Journal, recently disclosed Justice Department documents show that government prosecutors contemplated not only punishing the reporter who wrote the story, but staff and editors at the newspaper that printed it, too. It is worth noting that the Tribune at that juncture was published by interests unfriendly to the Roosevelt administration. A grand jury dismissed all charges against Johnston.”
