keystone pipeline

The oil leak occurs just a few days before Nebraska state regulators will decide on the fate of TransCanada's controversial sister project, the Keystone XL Pipeline.

Members of the North Dakota congressional delegation say the acting secretary of the Army has ordered the Corps of Engineers to proceed with an easement needed to complete the pipeline.

The pipeline would transport crude oil from Alberta to Nebraska. President Obama blocked it. President Trump told the company to refile for a permit and promised to speed the approval process.

The pipelines had been blocked by the Obama administration, and President Trump's actions reignited the energy vs. environment debate.
