ALL MY POINTS LEFT
During World War II, Presidential Executive Order 9066 and congressional statutes gave the military authority to exclude citizens of Japanese ancestry from areas deemed critical to national defense and potentially vulnerable to espionage. [Fred Toyosaburo] Korematsu remained in San Leandro, California, and violated Civilian Exclusion Order No. 34 of the U.S. Army. After his arrest and relocation, Korematsu appealed to the Supreme Court, citing that his internment was a violation of his basic rights as an American Citizen. The Supreme Court sided with the federal government in its decision.
