Following the attack on Pearl Harbor, President Franklin D. Roosevelt issued Executive Order 9066 on February 19, 1942. It required the forced relocation and internment of more than 110,000 Japanese Americans, most of whom were native-born American citizens. Congress appropriated funds for its implementation and provided penalties for its violation. In contrast, Congress approved legislation in 1943 to shore up relations with China, a key ally, and lifted restrictions on Chinese immigration to the United States for the first time since 1882.

We recommend the immediate evacuation of all persons of Japanese lineage . . . whose presence shall be deemed dangerous or inimical to the defense of the United States
