Denmark’s foreign minister had the top U.S. diplomat in the country summoned for talks after the main national broadcaster reported Wednesday that at least three people with connections to President Donald Trump have been carrying out covert influence operations in Greenland. Trump has repeatedly said he seeks U.S. jurisdiction over Greenland, a vast, semi-autonomous territory of Denmark. He has not ruled out military force to take control of the mineral-rich, strategically located Arctic island. Denmark, a NATO ally of the U.S., and Greenland have said the island is not for sale and condemned reports of the U.S. gathering intelligence there.
