I have looked at them, I've been following this since it started. And I agree that "And at least publicly nobody knows what is causing it" (but Id also add "or even if it's actually happening at all") that's why its dangerous to say things like what was said there. If I wanted to harm America, I'd start another cold war, a great way to do that would be to manipulate a war-hungry-revolving-door-to-defence-contractors organization into making public accusations against Russia on a continual basis.

Extraordinary claims require extraordinary evidence.
