President Donald Trump's interest in buying Greenland is "not a joke," Secretary of State Marco Rubio said in an interview on Thursday, adding that acquiring Greenland was in U.S. national interest and needs to be solved.

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 and influence in the Arctic and in Latin America.

President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.

President Trump still wants to acquire Greenland, and now the Danish leader is taking him seriously. President Trump and Elon Musk, two powerful figures, were initially united for the cameras and the "greater good," but their marriage made in heaven has now officially ended due to their conflicting ideologies and egos.

The secretary of State said purchasing the Danish territory is important to the country’s national interests in the Arctic.

Secretary of State Marco Rubio said on Thursday that President Donald Trump's offer to buy Greenland is “not a joke”, adding that acquiring the semi-autonomous Danish territory was in the US “national interest”.
