They're the 9th richest people in America and they're pushing hard to upend President Obama's progressive agenda. Billionaire brothers David and Charles Koch are the wealthiest, and perhaps most effective, opponents of President Obama's progressive agenda. They have been looming in the background of every major domestic policy dispute this year. David and Charles are also responsible for a vicious attack campaign aimed directly at obstructing and killing progressive reform. The Competitive Enterprise Institute, funded in part by Koch foundations, has waged an underhanded campaign to falsely charge that a set of hacked e-mails somehow unravels the scientific consensus that global warming is occurring. Fred Koch, father of Charles and David, helped to found the John Birch Society in the late 1950s. The John Birch Society harnessed Cold War fears into hate against progressives, warning that President Kennedy, Civil Rights activists, and organized labor were in league with communists.
