Three Washington, D.C., organizations most responsible for blocking comprehensive immigration reform in 2007 are part of a network of groups created by a man who has been at the heart of the white nationalist movement for decades, according to a report issued today by the Southern Poverty Law Center.

This report describes how the Federation for American Immigration Reform (FAIR), the Center for Immigration Studies (CIS) and NumbersUSA were founded and funded by John Tanton, a retired Michigan ophthalmologist who operates a racist publishing company and has written that to maintain American culture, "a European-American majority" is required.
