Michigan's business and labor leaders are calling on the Obama administration to approve the Keystone pipeline.
The long-delayed project to carry oil from Canada's oil sands to Texas Gulf Coast refineries has become a flashpoint in the climate change debate.
Groups like the Michigan Chamber of Commerce and Michigan Building and Construction Trades Council are joining some Republican and Democratic state legislators to push the project. They will hold a news conference Tuesday in the state Capitol to say the five-year wait since the initial application is long enough.
The pipeline wouldn't run through Michigan, but supporters say it would help the U.S. economy and be a step toward North American energy independence. Environmental groups say it would contribute to global warming, and they worry about a spill.
