White House Press Secretary Sarah Huckabee Sanders confirmed the act was lifted Thursday morning, and it “will go into effect immediately.”
Trump faced mounting calls to freeze the 97-year-old act, which requires products shipped between U.S. ports to be moved by American-owned ships.
That’s tied up getting critical supplies such as food, fuel and water to Puerto Rico, which has largely remained without power since Hurricane Maria made landfall last week.
Puerto Rico Gov. Ricardo Rossello said he petitioned the White House on Wednesday night to temporarily lift the ban.
The governor tweeted “Thank you” to the President’s official twitter account Thursday morning.
The White House previously lifted the act for southern states crippled by Hurricanes Harvey and Irma, allowing foreign ships to bring supplies to Texas and Florida
