Secretary of State Marco Rubio insisted that President Donald Trump’s talk about buying Greenland “is not a joke.” “This is not about acquiring land for the purpose of acquiring land,” Rubio said in an interview on Thursday with Megyn Kelly on SiriusXM.

Denmark said on Friday it meant seriously that Greenland is not for sale, after Secretary of State Marco Rubio said U.S. President Donald Trump's interest in acquiring the island was "not a joke". Trump says he will make the autonomous territory of Denmark a part of the United States,

"This is in our national interest and it needs to be solved," Rubio said. Greenland's prime minister has repeatedly said the island is not for sale.
