The State Department's inspector general's office will launch an inquiry into the department's decisions regarding the Keystone XL pipeline, which would ferry oil from Canada's tar sands formation across the Plains states to the Gulf of Mexico.
The inquiry, in response to a congressional request, will center on whether the department followed laws and regulations in preparing its environmental assessment and statement of national interest for the 1,700-mile-long pipeline.
