Good Question: What Is The Keystone XL Pipeline?
Earlier Tuesday evening, the U.S. Senate failed to approve the Keystone XL Pipeline by a vote of 59 - 41. Immediately after the vote, Republicans said they'd bring up the issue again in January. The fight over this pipeline has been a long, contentious battle that began in 2008 when TransCanada, the company building the pipeline, applied for a construction permit.
