On Friday, President Donald Trump extended a temporary waiver of the century-old Jones Act (Merchant Marine Act of 1920) for an additional 90 days. The move allows foreign-flagged vessels to transport fuel, oil, fertilizer, and other essential goods between U.S. ports, aiming to stabilize domestic supply chains and ease price pressures stemming from the ongoing U.S.-Israeli war with Iran and resulting disruptions in the Strait of Hormuz.
