The Federation for American Immigration Reform (FAIR) is the central nexus of the network of anti-immigration groups founded by John Tanton, an activist with white nationalist leanings and a fondness for extreme "population control" measures. Tanton founded FAIR in 1979 and remains a member of its advisory board; FAIR in many ways shapes the anti-immigration movement's policy priorities. FAIR staff and board members have over the decades occasionally expressed explicitly white nationalist views, and the group took more than $1 million from a eugenicist organization, the Pioneer Fund, in the 1980s and 1990s.
FAIR's legal arm, the Immigration Reform Law Institute (IRLI), has helped craft anti-immigrant legislation around the country, including Arizona's infamous "self-deportation" measure SB 1070 and efforts to end the 14th Amendment's guarantee of birthright citizenship.
