Michael Cohen, Trump's personal attorney, files lawsuits against Fusion GPS, BuzzFeed over infamous 'dossier'
It's difficult to see where his suit has any merit:
Against Fusion, he claims they "“recklessly placed [the dossier] beyond their control and allowed it to fall into the hands of media devoted to breaking news on the hottest subject of the day: the Trump candidacy.”
Well, yeah, of course they let it get out of their control. First of all, they could not control the outside consultant who researched and wrote the dossier (Steele). Then, they had to give it to their client, who paid for it. There was nothing they could do to stop the client or Steele. There is no evidence that Fusion leaked the documents. Steele himself leaked his findings both to the FBI and Mother Jones magazine.
Now if the lawsuit was against Steele or his company (Orbis), it would make sense, but there's really no reason to think Fusion did anything wrong or created any of the leaks that caused the dossier to become public.
Against BuzzFeed: (1) The dossier was obviously newsworthy, and BuzzFeed is a news organization (sort of), so they reported it; (2) BuzzFeed made no claim that the document was accurate, and in fact stated that "It is not just unconfirmed: It includes some clear errors."
