Verifies what? IMO Mueller is using the dossier as the road map for his investigation. If Brennan, Clapper, Comey, McCabe, Strzok, et.al., have conspired to frame Trump, I have some real concerns.
I am sure there has been a FBI file on Trump at least since his birther attacks on Obama in 2011. Trump humiliated Obama forcing him to produce his long form BC, which heretofore was denied existed. Arpaio did a thorough job of proving it was a phony document. Obama and DOJ then proceeded to go after Arpaio on trumped-up charges.
Deep State and Mueller are hell bent on destroying Trump. The dossier is central to this effort. If the majority of the allegations are somehow validated, then the actions of Deep State, including the FISA warrant and surveillance of the Trump campaign and transition teams as well as a sitting President will be validated. In that context, it is clear the incredible pressure being placed on Manafort, Cohen, Flynn, and others mentioned in the dossier is key.
The Reps must take the dossier seriously and do whatever is necessary to debunk it.
Of course, all those you mention have been involved are trying to get rid of our president. We here knew this immediately as soon as that absurdity was publicized. All that has been revealed since the beginning are details which do nothing to make the claims believable or any less absurd.
That dossier should be laughed out of court it is ludicrous from start to finish. Nothing but “unnamed sources”, “people close to ....”, “anonymous this...”, “anonymous that”, “sources close to major people..”
And the pretense that the authors of this poorly written report have gained nothing, it is just the opposite, making it clear that there was no collusion or meddling except on the part of the DNC and the FBI.
This dossier should be ridiculed at every opportunity, just about anytime a camera is trained on them.
