President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.

Senate Majority Leader John Thune said on Sunday that he believes President Donald Trump has made a "compelling argument" about Panama and Greenland.

Donald Trump insisted he was serious in his determination to take over Greenland in a fiery telephone call with Denmark’s prime minister, according to senior European officials.
