A journalist for the Chicago Tribune reported that "Navy Had Word of Jap Plan to Strike at Sea."
The Navy went after the Tribune, but the grand jury declined to return a true bill.
Still, the testimony before the grand jury has stayed classified since and one historian is trying to get that unsealed.
For the record, despite the Tribune's disclosure, the Japanese Navy never figured out that the US had broken the code. They kept using the broken code until 1945.
Funny to see a WW II court case still going on today.
