The conservative Frontiers of Freedom Institute has petitioned the Internal Revenue Service to rescind nonprofit status for the San Francisco environmental group Rainforest Action Network (RAN). The Arlington, VA-based research and education group--funded by the John M. Olin Foundation, the Bradley Foundation, and other right-wing foundations--has condemned RAN for being "fundamentally radical, anti-capitalist and lawless." Environmentalists worry this may have a chilling effect on activist organizations.
