The Russian collusion narrative has been completely debunked.

In a battle of "this narrative has been debunked" / "no it has not", the person who can provide links to inquiry on the narrative kinda prevails over the person who does not provide links to the debunk.

I say "kinda", in the sense that "it matters to people interested with dispassionnately learning about the subject", not "it will convince anyone to change their mind".
