"The presidential power to veto is one I take seriously ... and because this act of Congress conflicts with established executive branch procedures and cuts short thorough consideration of issues that could bear on our national interest — including our security, safety and environment — it has earned by veto."
First proposed more than six years ago, the Keystone XL pipeline project has sat in limbo ever since, awaiting a permit required by the federal government because it would cross an international boundary. The pipeline would connect Canada's tar sands with refineries on the Texas Gulf Coast that specialize in processing heavy crude oil.
Republicans and the energy industry say the $8 billion project would create jobs, spur growth and increase America's independence from Mideast energy sources. Democrats and environmental groups have sought to make the pipeline a poster child for the type of dirty energy sources they say are exacerbating global warming.
President Obama's administration, through the State Department, is still weighing the pipeline's merits, and he has repeatedly threatened to veto any attempts by lawmakers to make the decision for him. (The White House, The Hill, ABC News/AP, 2/24/2015)
