Authorities of Panama and Greenland have repeatedly said they won’t hand over any territory to Trump, with Panama’s president declaring that the canal "is going to stay in our hands forever," and Denmark’s prime minister insisting “Greenland is not for sale.”

President-elect Donald Trump on Tuesday said he would not rule out the use of military force to seize control of the Panama Canal and Greenland, as he declared U.S. control of both to be vital to American national security.

His rambling news conference included complaints about electric heaters that cause itching and lies about the criminal cases against him.
