A federal judge in Montana on Thursday temporarily blocked construction on the controversial Keystone XL pipeline, putting a hold on the Trump administration's permit for the project pending further environmental review. U.S. District Judge Brian Morris ordered the Trump administration to provide more comprehensive information on the pipeline's potential to contribute to greenhouse gas emissions, oil spills, and impact on Native American communities in its path. The 1,200-mile pipeline would transport oil south from Alberta, Canada. The decision was praised by environmentalists. It represented a major setback for the oil industry and President Trump, who reversed a decision by former President Barack Obama and approved the project in January 2017, promising it would provide jobs and boost the economy.
