Trump extends Jones Act waiver for 90 days, narrows scope

US President Donald Trump has extended for 90 days a waiver allowing foreign-flagged ships to transport oil and other commodities between US 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 extension, finalised on Monday, comes as the war with Iran disrupts global crude flows and pushes up fuel costs, increasing pressure on the administration to find ways to ease transport bottlenecks and keep petrol and other energy prices from rising further.The 90-day extension ensures the US military and key industries maintain uninterrupted access to critical resources, White House spokeswoman Taylor Rogers said on Monday.
