“Broad Jones Act waivers stifle the long-term capital investments essential to our commercial shipbuilding markets, maritime fleet, and domestic supply chains,” Paxton said. The American Maritime Partnership (AMP), a coalition supporting the Jones Act, struck a similar tone. Supporters of Jones Act reform seized on those voyages as evidence that the law itself restricts U.S. domestic commerce. With the additional 90 days, the exemption represents the longest suspension of the Jones Act in its more than century-long history. The reactions underscore the increasingly stark divide over what the unprecedented waiver means for the Jones Act itself.
