Jolie has pushed for legislation to aid child immigrants and other vulnerable children in both the U.S. and developing nations, including the "Unaccompanied Alien Child Protection Act of 2005." She began lobbying humanitarian interests in the U.S. capital from 2003 onwards, explaining, "As much as I would love to never have to visit Washington, that's the way to move the ball." Since October 2008, she has co-chaired Kids in Need of Defense (KIND), a network of leading U.S. law firms that provide free legal aid to unaccompanied minors in immigration proceedings across the U.S. Founded in a collaboration between Jolie and the Microsoft Corporation, by 2013, KIND had become the principal provider of pro bono lawyers for immigrant children. Jolie had previously, from 2005 to 2007, funded the launch of a similar initiative, the U.S. Committee for Refugees and Immigrants' National Center for Refugee and Immigrant Children.
