(AP) — President Donald Trump may have approved a federal permit for the Keystone XL pipeline, but the fight is far from over in Nebraska, the one state in its path that has yet to approve the project. The pipeline's fate once again rests with the Nebraska Public Service Commission, an independently elected group of four Republicans and one Democrat. The project's tangled history includes lawsuits, dozens of state and federal hearings, and threats of protests in Nebraska that could resemble the Dakota Access Pipeline showdown in North Dakota. If the commission approves the route, TransCanada could then initiate legal proceedings to gain access to the land owned by holdout property owners. Pipeline fighters are considering a campaign challenge against one commission member who represents a left-leaning district, said Jane Kleeb, executive director of the Bold Alliance, a group that opposes the Keystone XL. "The presidential permit for the Keystone XL is a welcome step forward to securing improved energy infrastructure in Nebraska and nationally, while also creating jobs and ensuring our energy independence," Ricketts said in a statement Friday.
