Shortly after his arrival, Trump Jr. was filmed on the phone with his father at a restaurant.

As one of Trump Jr.’s team held up the phone, the president-elect was heard saying that Greenland was a “very special place.”

“It needs security for itself, and it also urgently needs security for the world,” he said. “We need security and our country needs it and the whole world needs it,” he added before the crowd began to applaud.

Trump Jr. responded that his team is learning “a lot” and that Greenland is “incredibly beautiful.” He added that they were given a “spectacular” reception.

The Danish Foreign Ministry told NBC News that it “took note” of the visit but had no further comment because it was “not an official American visit.”

Danish Prime Minister Mette Frederiksen said Tuesday that Greenland’s future will be decided by Greenland and called the United States Denmark’s most important ally.

Her response echoed the clear stance of Greenland Prime Minister Múte Egede, who told Trump in December that “Greenland is not for sale.”

Still, the feud could lead to calls for Greenland’s independence from Denmark, with supporters hoping to “exploit Trump interest to pursue their own political goals” rather than replacing Danish authority with the Americans, Aagaard said.

Egede called on the territory to “free itself from the shackles of the colonial era,” adding that it would soon adopt a new self-government law to shape its own future independent of Denmark.

“We must not lose our long fight for freedom,” he said.

But in Denmark, most politicians found Trump Jr.’s visit “quite annoying,” Aagaard said, adding: “There is a clear Danish interest in keeping Greenland as part of the Commonwealth, although the Danes are aware of that Denmark can never defend Greenland alone.”
