The Daily Beast reports:
Speaking to reporters on the White House’s South Lawn in late July, President Donald Trump revealed that he was “looking at” a stop in Denmark after an upcoming trip to Poland to attend a World War II commemorative ceremony. For officials in Copenhagen, the comment came as a surprise.
Although it is customary in Denmark for there to be a standing invitation for the U.S. president — and though officials in both countries had been discussing the possibility of an American delegation visiting — no formal invitation had actually been extended to Trump.
By the next day, Queen Margrethe II had issued the invite, and the White House had officially announced the president’s plans to visit the country. Over the subsequent days, much planning went into preparing for the president’s visit, which was supposed to include meetings with high-level officials from Denmark, Greenland, and the Faroe Islands.
