It's no secret that Kris Kobach helped Arizona State Senator Russell Pearce write the Arizona law. Kobach works for the IRLI (Immigration Reform Law Institute), an arm of FAIR (Federation for American Immigration Reform).
Here's some background from the Southern Poverty Law Center:
At the center of the Tanton web is the nonprofit
Federation for American Immigration Reform (FAIR), the most important organization fueling the backlash against immigration. Founded by Tanton in 1979, FAIR has long been marked by anti-Latino and anti-Catholic attitudes. It has mixed this bigotry with a fondness for eugenics, the idea of breeding better humans discredited by its Nazi associations. It has accepted $1.2 million from an infamous, racist eugenics foundation. It has employed officials in key positions who are also members of white supremacist groups. Recently, it has promoted racist conspiracy theories about Mexico's secret designs on the American Southwest and an alternative theory alleging secret plans to merge the United States, Mexico and Canada. In 2006, a senior FAIR official sought "advice" from the leaders of a racist Belgian political party.

Kris Kobach, 41
Kansas City, Mo.
The man behind many of the deeply flawed anti-illegal immigrant laws passed recently is Kris Kobach, the "national expert on constitutional law" who works for the Immigration Reform Law Institute (IRLI). IRLI is the legal arm of the Federation for American Immigration Reform (FAIR),
recently listed as a nativist hate group by the Southern Poverty Law Center. At IRLI, Kobach has been a prime mover behind ordinances in Farmer's Branch, Texas, and Hazelton, Pa., among other places, that seek to punish those who aid and abet "illegal aliens."http://www.splcenter.org/get-informed/intelligence-report/browse-all-issues/2008/spring/the-nativists?page=0,11
