President Donald Trump has extended for 90 days a waiver allowing foreign-flagged ships to transport oil and other commodities between U.S. ports, but imposed new limits after shipbuilders and their allies in Congress argued the policy was undermining the domestic maritime industry, the White House said. The 90-day extension ensures the U.S. military and key industries maintain uninterrupted access to critical resources, White House spokeswoman Taylor Rogers said today. Under the new terms, the administration has narrowed the scope of the relief, requiring individual voyages to undergo case-by-case review rather than allowing foreign ships to receive blanket exemptions from the Jones Act, a White House official confirmed.
