President Donald Trump mocked the Kingdom of Denmark for allegedly increasing security around Greenland, telling reporters on Sunday that the country merely "added one more dog sled."

U.S. officials are expected to meet with Danish and Greenlandic counterparts in Washington, D.C. on Wednesday.

The leaders of Canada, France, Germany, Italy, Poland, Spain and the U.K. joined Denmark’s Prime Minister Mette Frederiksen on Tuesday in defending Greenland’s sovereignty in the wake of Trump’s comments about Greenland, which is part of the NATO military alliance.
