The Keystone XL pipeline is facing another federal lawsuit in Montana. The Rosebud Sioux Tribe has joined with the Fort Belknap Indian Community to challenge the Trump administration's permit for the pipeline. The tribes say the Trump state department violated the Administrative Procedures Act as well as federal laws protecting environmental and historical sites. This suit joins two others filed in Montana, now consolidated, since the Trump administration approved he pipeline in March 2017. SDPB's Victoria Wicks has this story.
