The eldest son of President-elect Donald Trump visited Greenland after his father refused to rule out military force to take control of the Arctic island.

President-elect Donald Trump’s eldest son, Donald Trump Jr., arrived in Greenland Tuesday for a personal visit as Trump has renewed his suggestion in recent weeks that the Danish territory should become part of the U.

President-elect Donald Trump has told residents of Greenland that “we’re going to treat you well” as his oldest son visited the mineral-rich Danish territory that’s home to a large U.S. military base.
