President Trump continues to demand control of Greenland after he criticized Norway over the weekend for not giving him the Nobel Peace Prize last year.

Overnight, Trump posted screenshots of private messages between him and the leaders of NATO and France online. In one, French President Emmanuel Macron said simply, "I do not understand what you are doing on Greenland." Trump also threatened additional tariffs over the weekend against eight European and NATO nations that have shown solidarity with Greenland.

Trump is traveling today to attend the World Economic Forum in Davos, Switzerland, where he’s expected to discuss the matter more.
