The State Department’s support of a controversial oil-pipeline project is putting pressure on the White House to move forward after three years, despite objections from environmentalists. A series of public hearings concludes Friday on the Keystone XL pipeline, which would run from Canada’s oil sands in Alberta down through America’s midsection to the Texas Gulf Coast. So far, the State Department has published reports in favor of the project, which is projected to create 20,000 jobs and reduce the nation’s dependence on overseas oil.
