I take this with a grain of salt. The 'source' (or sources) here are un-named and unclear if just the one or more.
The author, Seymour Hersh, has accused the Obama administration of lying about the events surrounding the death of Osama bin Laden, and disputed the claim that the Assad regime used chemical weapons on civilians in the Syrian Civil War.
This all sounds very plausible. It may even be true, but I do not trust the messenger that much.
