WASHINGTON - The Washington Post Monday reported that conservative billionaires Charles and David Koch have created a political network of "unrivaled complexity built around a maze of groups that cloaks its donors."
The report, conducted with help from the nonpartisan Center for Responsive Politics, said the Koch brothers and fellow donors created a network of politically active groups in 2012 for Republican conservatives that outpaced other independent groups on the right and matched the long-standing national coalition of labor unions that back Democratic candidates.
