Anti-pipeline push goes national

Primetime television viewers will get a quick look at the plain’s oil pipeline controversy in a new national television ad urging President Barack Obama to stop construction of the Keystone XL pipeline. The 30-second ad, paid for by the No Tar Sands Oil Coalition, portrays the Keystone XL decision as a chance to stop the next Gulf oil spill from happening, claiming that the “world’s dirtiest oil” would threaten the “Midwest’s most important drinking water source.” The U.S. State Department is expected to approve or deny TransCanada’s plan for the pipeline early next year.
