The Guardian reports: The Koch brothers’ conglomerate Koch Industries has refused to comply with an investigation by three Senate Democrats into whether the company has funded groups or researchers who deny or cast doubt on climate change.

In response to a request from senators Barbara Boxer, Edward Markey and Sheldon Whitehouse for information about Koch Industries’ support for scientific research, Koch general counsel Mark Holden invoked the company’s first amendment rights.

“The activity efforts about which you inquire, and Koch’s involvement, if any, in them, are at the core of the fundamental liberties protected by the first amendment to the United States constitution,” Holden wrote the senators in a letter dated 5 March and posted online by Koch Industries this week.

“I did not see any explanation or justification for an official Senate committee inquiry into activities protected by the first amendment,” he wrote, concluding, “we decline to participate in this endeavor and object to your apparent efforts to infringe upon and potentially stifle fundamental first amendment activities.”

Asked by the Guardian to elaborate on how the first amendment protects such funding and whether Koch Industries would pursue legal action to prevent disclosing information, Holden said: “Our letter speaks for itself.”

In his letter to the senators, Holden suggested that such funding represents part of “Koch’s right to participate in the debate of important public policy issues and its right of free association.”

On 25 February, the three Democratic senators – each a ranking member of committees that oversee environmental affairs – sent letters to 100 fossil fuel companies and thinktanks “to determine whether they are funding scientific studies designed to confuse the public and avoid taking action to cut carbon pollution, and whether the funded scientists fail to disclose the sources of their funding in scientific publications or in testimony to legislators.” [Continue reading…]
