Billionaire conservative icon David Koch is stepping down from the Koch brothers' network of business and political activities. David Koch is leaving his roles as executive vice president and board member for Koch Industries and a subsidiary, Koch Chemical Technology group, where he served as chairman and chief executive officer. Koch is also stepping down as chairman of the board for the Americans For Prosperity Foundation, the charity related to Koch brothers' primary political organization. Democrats have demonized the Koch brothers for their outsized influence in conservative politics over the last decade. David Koch, who served as the Libertarian Party's vice presidential candidate in 1980, had begun focus more on philanthropy in recent years.
