WASHINGTON—The federal government is once again urging a Michigan judge to keep Line 5 operating while it works with the United States on negotiating an end to the impasse over the controversial cross-border pipeline.
Gordon Giffin, the former U.S. ambassador to Canada who is serving as Ottawa’s counsel of record, filed a fresh amicus brief this week spelling out the stakes for both countries if the pipeline, owned and operated by Calgary-based Enbridge Inc., is shut down.
