The evidence strongly supports the statement that President Trump linked tariffs on Europe to the discussions about purchasing Greenland. The Deutsche Welle news report is a highly authoritative and relevant source that explicitly states EU leaders were discussing "Trump's latest tariff threat over Greenland," directly confirming that the two events were concurrent and connected in policy discussions. This establishes a clear link between the Greenland affair and a tariff action (in this case, a threat).The Wikipedia article on the proposed acquisition of Greenland, while a tertiary source, provides a crucial clue by citing a source with the title "Trump Calls Off Tariffs on Europe Over Danish Territory." This indicates that news outlets at the time reported on the tariffs being "called off" or "halted" in connection with this specific event. While the primary U.S. government sources (USTR, USITC) would provide the official record of tariff implementation or withdrawal, the provided news and research sources create a consistent and compelling narrative. The term "halted" is consistent with the idea of not proceeding with a threatened tariff, which the evidence suggests is what occurred. The irrelevant sources concerning a hypothetical future administration do not detract from the strength of the relevant evidence.
