U.S. Secretary of State Marco Rubio has met Panama's president on his first stop on his trip foreign trip as President Donald Trump is upping pressure on America's neighbors including a demand for the Panama Canal to be returned to the United States.

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.
