Curtis B Munson in 1941, a 'Businessman-turned-Spy' was commissioned by United States President Roosevelt to investigate and report upon the sympathies and loyalties of Japanese Americans living in California and Hawaii.
This report came about following the interception of messages from Tokyo to Japanese Americans in Hawaii requesting details about the U.S. Military Fleet stationed at Perl Harbour. The report found very little hostility amongst the Japanese American population, and portrayed them as loyal to America.
