In May 2011, U.S. Solicitor General Neal Katyal, after a year of investigation, found Charles Fahy had intentionally withheld The Ringle Report drafted by the Office of Naval Intelligence, in order to justify the Roosevelt administration's actions in the cases of Hirabayashi v. United States and Korematsu v. United States. The report would have undermined the administration's position of the military necessity for such action, as it concluded that most Japanese Americans were not a national security threat, and that allegations of communication espionage had been found to be without basis by the FBI and Federal Communications Commission.[96]
