The players in the Koch-backed $400 million political donor network

By Matea Gold

The Washington Post and the Center for Responsive Politics identified a coalition of allied conservative groups active in the 2012 elections that together raised at least $407 million, backed by a donor network organized by the industrialists Charles and David Koch. Most of the funds originated with two groups, the Freedom Partners Chamber of Commerce and TC4 Trust, both of which routed some of the money through a Phoenix-based nonprofit group called the Center to Protect Patient Rights (CPPR).
