Rep. Mike Waltz (R-FL) shared that conversations about the prospect of Greenland joining the United States are important from a national security perspective.

President-elect Donald Trump is the latest U.S. leader to attempt to bring Greenland and its population of over 50,000 among its territories. As Trump’s incoming national security adviser, Waltz said this could be the latest move in a tug-of-war with Russia and China over the Arctic.
