Citizens for a Sound Economy (CSE) was founded by David Koch in 1984, and split in 2003 into Americans For Prosperity and FreedomWorks.
FreedomWorks is an astroturf group led by former U.S. Representative Dick Armey, with a mission of promoting a conservative agenda. The astroturf group tries to cast doubt on the need for climate legislation, declaring: "organizations pushing action on global warming - such as the United Nations, the environmental movement, and former Vice President Al Gore - have substantial institutional, ideological, and financial stakes in creating a restrictive new layer of global warming regulation." FreedomWorks also participates in the echochamber around the "ClimateGate" story.
