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.

"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.

Rubio said he could not predict if Trump would succeed in buying Greenland from Denmark or restoring American authority over the Panama Canal while he is in office.
