Keystone XL Pipeline

FILE – This Nov. 3, 2015, file photo shows the Keystone Steele City pumping station, into which the planned Keystone XL pipeline is to connect to, in Steele City, Neb. Native American tribes in Montana and South Dakota say the Trump administration unlawfully approved the Keystone XL oil pipeline without considering potential damage to cultural sites. Attorneys for the Fort Belknap and Rosebud Sioux tribes sued the U.S. State Department Monday, Sept. 10, 2018, asking a court to rescind the permit. (AP Photo/Nati Harnik, File)
