"Snowden has had, and continues to have, contact with Russian intelligence services" (with no specifics). Yes, there are probably plants among the various Russian nationals he deals with. So what? (They make it sound like he's holding regular briefings with these people in a mahogany-paneled room somewhere).
"And in June 2016, [a Russian PM] asserted that 'Snowden did share intelligence' with his government." (That's not what the Russian PM, Frantz Klintsevich said -- and it's dishonest of the IC to assert otherwise). Also, this non-revelation was already made when the initial version of this problematic report was first published over the summer.
The overall weakness of these statements suggest that even now -- 3+ years after being stranded in Moscow, as a more or less direct result of the Obama administration's yanking his passport -- they still don't have anything to nail the guy with.
