FILE -This Dec. 5, 2012, file photo shows Sen. Mary Landrieu, D-La. on Capitol Hill in Washington. An indefinite extension to the government’s review of the contentious Keystone oil pipeline, announced late Friday, April 18, 2014, by the State Department, is doing little to quell the political posturing over the project, which has taken on a life of its own as climate change activists duke it out with energy advocates from both parties. For Landrieu, whose competitive race in Louisiana will help determine whether Democrats retain control of the Senate, the delay comes at a particularly sensitive moment. Landrieu recently took the helm of the Senate Energy Committee, and has been touting her new position to argue that she offers voters in oil-dependent Louisiana the best chance to influence America’s energy policies _ including approval of Keystone XL.
