The fact that the Orange Geezer has categorically denied that this could possibly be true, without any basis for knowing one way or the other, is highly suspicious. How could it possibly be to his advantage to deny the link? The claim, all along, was not that the Russians won the election for him. The claim was always only that the Russians hacked and meddled in the election. 

The fact that the geezer's camp desperately wants this to go away suggests that they have something to hide and/or that they are completely insecure and paranoid about the validity of the election. Time will tell which of these is the case. Either way, Trump is looking like a chump and a fool.
