Watch Full Movie Online. Koch Brothers Exposed is a hard-hitting investigation of the 1% at its very worst. This full-length documentary film on Charles and David Koch—two of the world’s richest and most powerful men—is the latest from acclaimed director Robert Greenwald (Wal-Mart: the High Cost of Low Price, Outfoxed, Rethink Afghanistan). The billionaire brothers bankroll a vast network of organizations that work to undermine the interests of the 99% on issues ranging from Social Security to the environment to civil rights. This film uncovers the Kochs’ corruption—and points the way to how Americans can reclaim their democracy.
