Donald Trump has lashed out at the Danish Prime Minister during a "horrendous" 45-minute phone call as the duo discussed Greenland's future. The heated discussion has been described as "explosive" and was driven by Trump's demand that securing Greenland was required for national security purposes.

The story goes that Trump and Frederiksen spoke on the phone last week for about 45 minutes in what was expected to be a bit of a feeling-out between the two parties, given Trump’s very public declaration that he would like to take Greenland off Denmark’s hands.

Danish officials, who wished to stay anonymous, spoke to the Financial Times after Trump had a call with Danish Prime Minister Mette Frederiksen. They claimed the president was fiery, aggressive, and confrontational, despite the offer to increase Greenland-US cooperation on military bases and natural resources.
