If the story is true. If it's a fabrication - as they allege, and given that Fox News passed on it (https://www.independent.co.uk/news/world/americas/us-electio...) and the Post's reporter didn't want his byline on it (https://www.nytimes.com/2020/10/18/business/media/new-york-p...), seems reasonably likely - they didn't hear about it until last week.
