The evidence strongly supports the truthfulness of the statement. Multiple high-authority primary sources, including reports from the Wall Street Journal and Bloomberg News, directly state that Donald Trump said he was 'not concerned' about the decline of the US dollar. This is the core of the claim and is explicitly verified by sources 1, 2, and 3.Furthermore, a significant body of corroborating evidence from sources like the Financial Times, MarketWatch, The Japan Times, and Yahoo Finance reinforces this position. These sources repeatedly quote Trump from a Wall Street Journal interview stating that the dollar was 'too strong' and that its strength was 'killing us.' This sentiment is perfectly consistent with a lack of concern over the dollar's decline; in fact, it implies that a decline would be a desired outcome to achieve his stated economic goals. An academic source also confirms that a weaker dollar was part of his administration's economic strategy.There is no contradictory evidence provided in the sources. All available information points to the same conclusion: Donald Trump publicly and repeatedly expressed a preference for a weaker dollar, which logically aligns with the specific statement that he was not concerned about its decline. The consistency and high authority of the sources lend high confidence to this assessment.
