ZEMBLA - The dubious friends of Donald Trump: the Russians

This is interesting but I wish it was better sourced. For example: at about 18 minutes in, they start talking about Felix Sater's criminal trial and then state that he became an informant and the transcript was sealed. Well, if the record was sealed, how do they know what was in it? What was their source? They don't even mention an "unnamed source" or anything like that.

There are a number of similar minor anomalies. I don't doubt that most of this is true but I just don't like unsourced allegations.  

That NY prosecutor does seem entirely credible, however, so I don't quite know what to make of it. If he's got a case, why isn't it in court?
