U.S. Senator Heidi Heitkamp speaks with Mary Delaquis, who for 16 years was on the front lines of securing North Dakota’s busiest port of entry as Pembina’s Area Port Director. Then, Heitkamp talks to author Porter Fox, who traveled the Northern Border by canoe, car, freighter, and foot. Fox illustrates the vastness of the border and challenges we face to secure it in his book, Northland: A 4,000-Mile Journey Along America's Forgotten Border.
