What was the official position of the US government concerning the treatment of Japanese Americans during world war 2?

During World War II, the official position of the U.S. government was that the internment of Japanese Americans was a necessary measure for national security. In 1942, President Franklin D. Roosevelt signed Executive Order 9066, which led to the forced relocation and internment of around 120,000 Japanese Americans, most of whom were U.S. citizens. The government justified this action on the basis of wartime fears of espionage and sabotage, despite a lack of evidence to support such claims. This policy has since been widely criticized and recognized as a violation of civil liberties.
