Gretchen Whitmer is taking proactive measures to shut down a Canadian oil and gas pipeline, a move that could embroil America and its northern neighbor in a conflict. Whitmer, a Democrat, claims her efforts to close an underwater pipeline, owned by Calgary-based Enbridge Inc., will protect the Great Lakes and area jobs, calling two 4.5 mile sections of the pipeline a "ticking time bomb." For nearly 67 years, Enbridge has moved oil and natural gas from western Canada through Michigan and the Great Lakes to refineries in the province of Ontario.
