President Trump sent out a statement on Twitter today, reminding that he had given the order to help Argentina.

The search for an Argentine navy submarine that vanished on November 15 with a 44-member crew on board has now reached a “critical phase,” as concerns are mounting that it is now running out of oxygen.

Reportedly, at least 4,000 people from Argentina, the United States, Brazil, Chile and Britain have all joined in the search using aircraft and ships, as family members wait in anguish.

As of the last radio contact with the submarine on Nov. 15, it was off the coast of Patagonia on a routine security patrol.

“I have long given the order to help Argentina with the Search and Rescue mission of their missing submarine. 45 people aboard and not much time left. May God be with them and the people of Argentina!” Trump tweeted Wednesday afternoon.

President Trump also tweeted about the millions of Americans who are traveling this weekend for Thanksgiving.

“51 Million American to travel this weekend – highest number in twelve years (AAA). Traffic and airports are running very smoothly! @FoxNews,” he wrote.

Trump also re-tweeted a Twitter post from First Lady Melania Trump, with pictures of the White House being decorated for the holidays.
