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.

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.

Anders Vistisen, a Danish member of the European Parliament, has told U.S. President Donald Trump to "f*** off" after Trump again expressed interest in purchasing the island of Greenland. Newsweek has contacted the White House for comment via email.
