We must scrupulously guard the civil rights and civil liberties of all citizens, whatever their background. We must remember that any oppression, any injustice, any hatred, is a wedge designed to attack our civilization.

Franklin Delano Roosevelt (1882-1945) American lawyer, politician, statesman, US President (1933-1945)

Letter to William Allan Neilson (1940-01-09)
    (Source)

Neilson was the co-chair of the Sponsor Committee, Fourth Annual Conference of the American Committee for Protection of Foreign-Born. It was read to the conference on 1 March 1940, and entered into the Congressional Record (along with other letters received) on 11 March.

About two years later, 19 February 1942, FDR signed Executive Order 9066, authorizing the evacuation of all persons (which largely meant Japanese-Americans) deemed a national security threat from the West Coast to internment centers further inland.
