Trump made it clear that he was "serious" about acquiring Greenland, but Danish PM Mette Frederiksen rejected the idea outright, stating Denmark was not interested in "selling" the mineral-rich island.

The story goes that Trump and Frederiksen spoke on the phone last week for about 45 minutes in what was expected to be a bit of a feeling-out between the two parties, given Trump’s very public declaration that he would like to take Greenland off Denmark’s hands.

President Trump reportedly held a “fiery” call with Denmark’s Prime Minister Mette Frederiksen over the president’s insistence that U.S. control of Greenland is necessary for American national security.
