Denmark summoned the U.S. charge d’affaires over a report alleging a U.S. influence operation in Greenland.

A Tuesday report from DR, Denmark’s public broadcaster, citing Danish intelligence sources, alleged that President Donald Trump’s allies were carrying out an “infiltration” and “influence operation” in Greenland, seeking to weaken the island’s ties with Copenhagen and open it to a U.S. takeover. In response to the report, Danish Foreign Minister Lars Lokke Rasmussen summoned the U.S. charge d’affaires for a meeting at the ministry.
