Koch Brothers

Charles Koch says he's not really spending all that much on politics. As one of the billionaire Koch brothers, Koch has made massive infusions of money to political causes — some of it in direct contributions to candidates, and much of it through support for think tanks and other political groups. The organization of donors led by Charles and his brother David has vowed to spend $889 million to influence the 2016 election.

Yet in an interview with NPR, Charles Koch suggested he is merely playing defense, not offense. The libertarian-leaning industrialist said he is outspent.
