John Hoeven, R-N.D., sponsor of the Keystone XL pipeline bill, on Capitol Hill in Washington, Thursday, Jan. 29, 2015, after winning a critical procedural vote on the measure. The Republican-controlled Senate moved toward passage of a bipartisan bill approving the Keystone XL oil pipeline, getting enough votes to overcome a filibuster, 62-35, but it remains five votes short of a veto-proof majority.
