美国10月财政赤字扩大至2840亿美元

The assessment is based on a high degree of consistent evidence from multiple, credible sources. Several reputable news organizations, including Reuters, Yahoo Finance, and Fidelity, directly and explicitly state that the U.S. fiscal deficit for October was $284 billion. These secondary sources are all rated with high authority and relevance, and they all appear to be reporting on the same primary data from the U.S. Treasury Department's "Monthly Treasury Statement."While the provided link to the U.S. Department of the Treasury is its homepage and not the specific report, it is correctly identified as the ultimate authority on the matter. The existence and name of the official report are further corroborated by a Morningstar article. There is no conflicting information across any of the provided sources; the less relevant sources do not contradict the claim but are simply off-topic. The overwhelming consensus among the highly relevant and authoritative secondary sources makes the statement very likely to be true.
