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.

Secretary of State Marco Rubio says President Donald Trump’s desire to acquire Greenland and retake control of the Panama Canal is driven by legitimate national security interests stemming from growing concerns about Chinese activity in the Arctic and in Latin America.

"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.
