Knowledge and Progress Fund
The Knowledge and Progress Fund (KPF) is one of several Koch Family Foundations, and is controlled by Koch company director Richard Fink (President). Charles Koch, his wife Elizabeth B Koch, and his son Charles Chase Koch are all on the KPF board. The Koch brothers are co-owners of Koch Industries, the largest privately-owned energy company in the United States. SourceWatch describes the Koch brothers as “key funders of the right-wing infrastructure, including the American Legislative Exchange Council (ALEC) and the State Policy Network (SPN).” 
A report by the Center for Public Integrity found that the Knowledge and Progress Fund was one of the largest known contributors to the secretive Donors Trust. KPF donated over $13 million from 2001 to 2014 to either Donors Capital Fund or Donors Trust, according to public tax records. A 2015 investigation by Desmog found that DCF and DT reported an income of more than $511 million between 2005 and 2011, with some $479 million of that income coming from individuals who do not have to declare their donations. , 
Donors Trust and its sister organization Donors Capital Fund (DCF) obscure the identity of individual donors through “donor-advised funds,” allowing donors to anonymously give to conservative causes. Mother Jones magazine described the groups as “the dark-money ATM of the conservative movement.”  In recent years, KPF's only activity has been to make donations to either DT or DCF.
Bill of Rights Institute
According to public tax records, before 2004, the Knowledge and Progress Fund operated as a 501(c)(3) charitable organization in Arlington, Virginia. According to KPF's 2004 form 990, “Prior to 9-1-2004, Knowledge and Progress Fund, Inc. filed a form 990. Converted to a private foundation and made a change in accounting period 9-1-2004.” In 2004, KPS also moved to new location in Wichita, Kansas.
Sourcewatch notes that until its move in September of 2004, the Knowledge and Progress Fund was tied to the Bill of Rights Institute, another organization backed by the Koch brothers. When the Knowledge and Progress fund converted to a private foundation in 2004, it ended its official relationship with the Bill of Rights Institute. , 
Mark Humphrey, a current director of the Bill of Rights Institute, was the secretary of the Knowledge and Progress Fund from 2003 to 2008 (see 990 forms below) and a senior vice president of Koch Industries. ,
