FILE - In this Jan. 23, 2013, file photo, Sen. John Hoeven, R-N.D, points at a illustration of existing pipeline, while speaking at a news conference about the Keystone XL oil pipeline on Capitol Hill in Washington. The State Department on Friday, March 1, 2013, raised no major objections to the Keystone XL oil pipeline and said other options to get the oil from Canada to U.S. Gulf Coast refineries are worse for climate change. But the latest environmental review stops short of recommending whether the project should be approved.  (AP Photo/Jacquelyn Martin, File)
