Some of the Senate’s most liberal Democrats, demanding that 22 national and state-based think tanks disclose their donors, disparaged them as being part of a network of free-market policy organizations the senators accuse of “laundering” identities while denying climate change exists.
The existence of the conservative and libertarian policy research and education organizations, Senate Minority Leader Harry Reid and eight fellow senators wrote in a letter to some of the organizations’ leaders, suggests the extent of a “web of denial” about man’s contribution to global warming, or climate change.
“Because your organizations do not regularly disclose where your donations come from, we cannot know for sure how deep and wide the web of denial truly is,” the nine senators write.
