On February 19, 1976, President Gerald Ford signed the proclamation “An American Promise.” It formally announced the termination Executive Order 9066, the measure that had resulted in the uprooting of Japanese Americans and their detainment in camps during World War II.
Although E.O. 9066 had ceased to be effective once hostilities had ended, the Japanese American Citizens League and others petitioned the White House to have the termination officially recognized.
