Original sentence: Famously, Congressman Barton stated his opposition to Cap and Trade legislation because (contrary to verifiable fact) he believed CO2 to be harmless at all concentrations, further believed it had no ill effects on human life and was a substance which had never resulted in a death or hospitalization.He has been called the face of Climate Change Doubters.He is equally notable for leading the opposition to both the 2009 public option and single payer proposals in Health Insurance Reform.Some believe that an estimated $2,600,000 in donations from the Health Insurance, Pharmaceutical, and related industries may have influenced his objection to these proposals for affordable, efficient, portable health insurance for American workers
