In addition to the billions they’re spending to elect wingnuts who will cut their taxes and deregulate, the Koch brothers have also been on a spending spree at colleges and universities. According to a new report from the Center for Public Integrity (below) the brothers Koch invested more than $19.3 million across 210 college campuses in 46 states in 2013 alone. That money comes with strings, of course. At the College of Charleston, the Charles Koch Foundation sought names and email addresses of any student participating in a Koch-sponsored class, and to be notified in advance of media outreach related to the school. And as I’ve previously noted, the Foundation’s pledge of $1.5 million to Florida State University’s economics department stipulated that a Koch-appointed advisory committee would select professors and undertake annual evaluations.In other words, the Koch brothers aren't just trying to buy American democracy. They're also seeking to buy American minds.
