I read this article from Buzzfeed when it came out in January and because it came from a former, credible, high-level British spy (now working for profit), I gave it some consideration. (John McCain was given these confidential reports; he forwarded them to James Comey. Comey already had them).
But re-reading this confidential report 5 months later, it seems to make a lot of sense with the names we've been seeing in the media.
Yes, Donald Trump can claim he's had no personal profit from Russia.
But these reports claim Trump has a sexual perversion; which the Russians would use as they set him and prostitutes up. If so, there are video tapes somewhere in Putin's possession.
We're not hearing about these allegations. Again, 5 months after this was released, it seems to make sense.
