You mean like the video that didn't exist showing Rob Ford smoking crack with drug dealers.  This is following exactly the same path as that tragedy.   First vehement denials, then rumours of a video, then out it comes.

If you look at the back story to that dossier the MI6 fellow, who is now in hiding produced it refers to a contact in the Russian FSB.  That contact was found dead a few weeks back.   Where there is smoke there is fire and while both sides are desperately trying to suppress the smoke my guess is someone in the CIA has a copy of the material which can bring down this President.   It is only a matter of timing.  They need to allow Trump to make a few more serious gaffes and then the facts in the dossier become 'live'.

The other strange thing is the guy who helped out Ford, Daniel Dale , is now a Washington, DC correspondent for the Star.
