116. Cass Sunstein

Cass Sunstein has long been one of Barack Obama’s closest confidants. Often mentioned as a likely Obama nominee to the Supreme Court, Sunstein is currently Obama’s head of the Office of Information and Regulatory Affairs where, among other things, he is responsible for “overseeing policies relating to privacy, information quality, and statistical programs.” In 2008, while at Harvard Law School, Sunstein co-wrote a truly pernicious paper proposing that the U.S. Government employ teams of covert agents and pseudo-”independent” advocates to “cognitively infiltrate” online groups and websites — as well as other activist groups — which advocate views that Sunstein deems “false conspiracy theories” about the Government. This would be designed to increase citizens’ faith in government officials and undermine the credibility of conspiracists.
