Heated Call Between Trump and Frederiksen A “fiery” phone call between Donald Trump and Danish Prime Minister Mette Frederiksen has escalated tensions. Reports from the Financial Times describe the conversation as “horrendous,” with Trump maintaining a firm stance on Greenland’s importance to the US. Frederiksen, however, reiterated that Greenland is not for sale, emphasizing the autonomy and wishes of its 56,000 residents.
