On February 17, 2013, approximately 35,000 to 50,000 protesters attended a rally in Washington, D.C. organized by The Sierra Club, 350.org, and The Hip Hop Caucus, in what Bill McKibben described as "the biggest climate rally by far, by far, by far, in U.S. history". The event featured Lennox Yearwood; Chief Jacqueline Thomas, immediate past chief of the Saik'uz First Nation; Van Jones; Crystal Lameman, of Beaver Lake Cree Nation; Michael Brune, Sen. Sheldon Whitehouse (D-RI), and others as invited speakers.
