The White House announced early Thursday that President Trump has agreed to waive the Jones Act, which will temporarily lift shipping restrictions on Puerto Rico and enable the hurricane-ravaged island to receive necessary aid.

The waiver from the shipping law, which requires American-made and operated vessels to transport cargo between U.S. ports, will only last for 10 days and goes into effect immediately.

“At @ricardorossello request, @POTUS has authorized the Jones Act be waived for Puerto Rico. It will go into effect immediately,” White House press secretary Sarah Huckabee Sanders wrote on Twitter, referring to Puerto Rico Gov. Ricardo Rosselló.

Lawmakers in Congress since Monday have been pushing for a one-year waiver from the rules in an order to help speed up deliveries of food, fuel and other critical supplies to Puerto Rico, which has been battered by two hurricanes in the last month. Officials estimate that the island could be without power for six months.
