Donald Trump Criticizes Federal Reserve Chair Jerome Powell and Mentions Possible Lawsuit

The evidence strongly supports both components of the statement. The first part, that Donald Trump criticized Jerome Powell, is confirmed by multiple high-authority sources. The New York Times notes that Powell was a "frequent target" of Trump's criticism, and other news sources corroborate this. The second, more specific part of the claim, regarding a potential lawsuit, is directly and explicitly supported by a high-authority Barron's article which states that Trump threatened to sue Powell for "gross incompetence." This is further substantiated by a highly respected legal blog, SCOTUSblog, which mentions potential "legal action" involving the Federal Reserve's Board of Governors. While several other sources do not mention the lawsuit threat, none of the provided sources contradict it. The consistency across the most relevant and authoritative sources makes the overall statement very likely to be true.
