About Capital Research Center
Founded in 1984, Capital Research Center is a think tank that exists to "examine how foundations, charities, and other nonprofits spend money and get involved in politics and advocacy, often in ways that donors never intended and would find abhorrent," according to its website.
CRC says it is "not afraid to take on the Washington Establishment—Republican, Democrat, or anyone else."
