In a reversal of the position taken by his predecessor, President Donald Trump is expected to take executive action today to advance construction of the Keystone XL and Dakota Access oil pipelines, according to multiple news reports and a source with knowledge of the action.  The president is scheduled to sign orders at the White House late this morning.
Former President Barack Obama killed the proposed Keystone XL pipeline in late 2015, declaring it would have minimal positive impact on job creation, energy independence or environmental protection, while undercutting U.S. efforts to clinch a global climate change deal that was a centerpiece of his environmental legacy.  The pipeline would run tar sands from Canada through the U.S. to refineries in the Gulf Coast, where the Canadian fossil fuel would be shipped to other countries.  The U.S. government needed to approve the international pipeline.
