Environmental group Friends of the Earth (FOE) last week sued the State Department for access to communications between it and lobbyists promoting the Keystone XL tar sands pipeline, two of whom were prominent fundraisers for the 2008 presidential campaign of Secretary of State Hillary Clinton. That project, in which Canadian oil company TransCanada wants to build nearly 2,000 miles of pipeline to carry tar sands oil from Alberta, Canada, to refineries on the Gulf of Mexico, requires a presidential permit from the State Department. FOE originally filed a Freedom of Information Act (FOIA) request for the materials in 2010.
