Southerners in Congress kept the New Deal segregated, so that black people were largely excluded from policies regarding labor, housing, education. The newly created Social Security Administration, for example, excluded the two largest categories of black workers, those laboring on farms and in domestic service. The military, of course, remained either segregated (Army, Navy) or exclusionary (Marines, Air Force). African Americans got the worst of it, and President Roosevelt also balanced the interests of his Jewish constituencies against the preferences of his Catholics, as in the case of the radio priest Father Charles Coughlin.
