"She's not talking to me, she's talking to the United States of America," Mr. Trump told reporters on the South Lawn of the White House.
"You don't talk to the United States that way," as the President repeatedly threw transatlantic elbows at Prime Minister Mette Frederiksen.
“I thought that the Prime Minister's statement that it (the sale of Greenland) was an absurd idea, was nasty," Mr. Trump added.
In Denmark, the Prime Minister did not return the President's verbal jabs, as she told reporters the visit would have been an opportunity to further broaden Danish relations with the U.S. Government.
"It was an opportunity I think to celebrate Denmark's close relationship with the U.S.," Frederiksen said.
The Queen of Denmark had invited the President and First Lady for a two day state visit in early September.
