area, and put up digital billboards along the Eisenhower Expressway in Maywood, Illinois, featuring a photo of Ted Kaczynski, the "Unabomber" whose mail bombs killed three people and injured 23 others, asking the question, "I still believe in global warming, do you?" They withdrew the billboards a day later. The institute planned for the campaign to feature murderer Charles Manson, communist leader Fidel Castro and perhaps Osama bin Laden, asking the same question. The institute justified the billboards saying "the most prominent advocates of global warming aren't scientists. They are murderers, tyrants, and madmen." The billboard reportedly "unleashed a social media-fed campaign, including a petition from the advocacy group Forecast the Facts calling on Heartland's corporate backers to immediately pull their funding," and prompted Rep. James Sensenbrenner Jr. (R-Wis.) to threaten to cancel his speech at the upcoming seventh International Conference on Climate Change organized by Heartland. Sensenbrenner ultimately did speak at the conference. Within 24 hours Heartland cancelled the campaign, although its president refused to apologize for it. The advertising campaign led to the resignation of two of the institute's 12 board members, and the resignation of almost the entire Heartland Washington D.C. office, taking the institute's biggest project (on insurance) with it. The staff of the former Heartland insurance project founded the R Street Institute and announced they "will not promote climate change skepticism." Following the 2012 document leak and the controversial billboard campaign, substantial funding was lost as corporate donors, including the General Motors Foundation, sought to dissociate themselves from the institute. According to the advocacy group Forecast the Facts, Heartland lost more than $825,000, or one third of planned corporate fundraising for the year. The shortfall led to sponsorship of the institute's May 2012 climate conference by Illinois' coal lobby, the Illinois Coal Association, the institute's "first publicly acknowledged donations from the coal industry," and the Heritage Foundation. The billboard controversy led to the loss of substantial corporate funding, including telecommunications firm AT&T, financial service firm BB&T, alcoholic beverage company Diageo and about two dozen insurance companies, including State Farm and the United Services Automobile Association. Pharmaceutical companies Amgen, Eli Lilly, Bayer and GlaxoSmithKline ended financial support. Heartland's May, 2012, climate conference was smaller than previous years. Repeal of mandates on renewable energy The institute wrote model legislation to repeal mandates on renewable energy, such as solar and wind power, and presented the model legislation to
