Sen. John Hoeven, R-N.D., sponsor of the long-stalled Keystone XL pipeline bill, strides to the Senate floor for a roll call vote as the Republican-controlled Senate moves ahead on a bill to construct the Keystone XL pipeline despite President Barack Obama's veto threat, at the Capitol in Washington, Monday, Jan. 12, 2015. The measure has sparked intense debate over the Canada-to-Texas pipeline's potential impact on employment and the environment, yet there was little or no doubt that it would overcome the vote to proceed on the bill Monday night. Republicans said they hoped it could win final approval and be sent to the White House by the end of next week. (AP Photo/J. Scott Applewhite)
