Social media posts claimed Denmark deliberately chose the tune, a knock often read as mocking someone, right before President Donald Trump joined Danish Prime Minister Mette Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen for the signing ceremony. The claim spread across X, Bluesky, Facebook and Instagram, with one X post alone pulling more than 1.3 million views. One widely shared video zooms in on Secretary of State Marco Rubio as the song plays in the background.
The denial hasn't slowed the claim down online, where it keeps getting reshared as evidence of a diplomatic dig aimed at the American delegation.
The dispute matters because the signing itself covers serious ground, a security arrangement between the US and Greenland, negotiated with Denmark in the room. A viral rumor about a show tune now threatens to overshadow the substance of the deal, turning a diplomatic milestone into a fact-check story instead.
