US District court temporarily halts construction of Keystone XL oil pipeline

The administration overturned a ruling by the Obama administration in 2015 that denied a permit for the pipeline, largely on environmental grounds.

A federal judge on Thursday halted construction of the Keystone XL oil pipeline, arguing that President Donald Trump's administration had failed to adequately explain why it had lifted a ban on the project.

The ruling by Judge Brian Morris of the US District Court for the District of Montana dealt a stinging setback to Trump and the oil industry and served up a big win for conservationists and indigenous groups.

Trump granted a permit for the conduit meant to stretch from Canada to Texas shortly after taking office. He said it would create jobs and spur development of infrastructure.

Thursday's ruling is temporary and requires the government to do a more thorough review of how the project might affect the climate, cultural resources and wildlife.
