Seymour Hirsch has an excellent track record, by the way, for exposing the military industrial complex going back to the first Iraq war. But Facebook doesn't want his reporting shared. They are censoring this story. And who is Facebook relying on to fact check this story? Is it someone with more credibility and a better track record than Seymour Hirsch?
