Trump’s interest in buying Greenland was first reported on Thursday by The Wall Street Journal. The Journal reported that people familiar with the deliberations said the President has raised the issue during meetings and dinners, asking aides and listening seriously about the possibility and advantages of owning Greenland. He also asked his White House counsel to research the matter, according to two of the people.

Two of the people also told the Journal that Trump’s aides were divided on the issue, with some praising it as solid economic strategy and others dismissing it as a passing fancy.

CNN has contacted the White House and the State Department for comment. But the island’s government on Friday flatly ruled out such a purchase in a statement: “Greenland is not for sale.”
