Which parts are supposition?
I read the whole thing top to bottom twice in an attempt to figure that out. Everything is either uncontroversial or has well-documented sourcing.
The only thing I can see setting off anyone is this:
Allegations by U.S. intelligence agencies that Russian actors were behind hacking of senior Democratic Party operatives and spreading disinformation linger over Trump’s young presidency. Democrats charge the Russians wanted to tilt the election toward the Republican, a claim dismissed by Trump. Russia denies the allegations.
It’s treated like a he-said, she-said. You’ve got unnamed intelligence agencies and Democrats on one side, and Trump and the Russians on the other. Equally weighted, fair and balanced. They didn’t name all 17 of the intelligence agencies, to avoid tipping the field. Reuters is usually pretty conservative, but this is only a slight pro-Trump tilt.
That would be it. The DNC still has not given it’s servers to the FBI to examine (and they asked) so I am unsure as to how they can actually keep making the claim. There is no fool proof evidence from anyone at this juncture that can accurately prove or disprove that Trump is a liar and that the Russians lost Clinton the election. None.
