The science envoy for the U.S. State Department, Dan Kammen, has resigned in protest of President Trump’s refusal to quickly condemn the deadly white supremacist violence in Charlottesville, Virginia, earlier this month. In his resignation letter, Kammen writes, “Your presence in the White House harms the United States domestically and abroad and threatens life on this planet.” The first letter of each paragraph of his resignation letter spells out the word “impeach.” This is now-resigned science envoy Dan Kammen, speaking to Democracy Now! during the 2016 climate change conference in Marrakech, Morocco, just after President Trump was elected.

Dan Kammen: “To be a climate denier in 2016 is to simply ignore science. A businessman is supposed to be flexible and thoughtful about opportunity. Clean energy is an economic boon, and it’s a boon for equity around the planet. And to turn your back on that is to put ideology over simple, good clean energy business and clean energy jobs.”
