The philanthropic Open Society Foundations run by George Soros sought in 2010 to foster an alliance between civil liberty advocates and proponents of illegal immigration in order to block comprehensive immigration reform, and language that would have required closer tracking of immigrants, hacked documents reveal.

The move was made after an off-the-record meeting in November 2009 between representatives of Soros’ organization and groups that included the American Civil Liberties Union, the Human Rights Campaign, the National Immigration Law Center, and the libertarian Cato Institute.
