What president used executive orders to reduce the right of certain citizens during wartime?

President Franklin D. Roosevelt used executive orders during World War II to reduce the rights of certain citizens, most notably through Executive Order 9066. This order led to the internment of Japanese Americans, forcing them into relocation camps due to fears of espionage and sabotage. The decision was justified at the time as a national security measure, but it has since been widely criticized as a violation of civil liberties.
