Presidential candidates weigh in on the feud over Norwegian Air

Democratic presidential front-runner Hillary Clinton has jumped into the dispute over whether Norwegian Air International is competing fairly against its U.S.-based rivals — and she is taking a position critical of the Obama administration.

Norwegian Air, a subsidiary of Norway-based Norwegian Air Shuttle, one of Europe's biggest low-cost carriers, has been accused by U.S.-based carriers and their unions of skirting U.S. and European labor laws by establishing a base in Ireland but hiring pilots out of Asia to save money.

Norwegian has denied the charges, and a report by the U.S. Department of Transportation said the agency investigated and found no basis to deny Norwegian a permit to fly to the U.S. from Ireland on that basis.
