I never understood why the Dossier was such a big deal. If he a) cavorts with Russian prostitutes (not illegal, just looks bad) who he pays to pee on the bed (gross and unhealthy but, again, not illegal) in a bed that Obama once slept in (seriously, who the hell cares?) and it might cause someone to look for a different candidate but in no way is this something that could send him to jail any more than if Obama had a dossier with reported homosexual affairs before being elected.
I think the whole point of leaking the Dossier was to offend moralists and blacks.
BTW, it should be noted that Trump now pees in places Obama once used - oh, the scandal!
There is the real takeaway from this story. It was the Democrats who colluded with foreigners making up stories about the Russians to affect the election.
