Given the current political atmosphere and the way the alt-right media have acted by making up things after big events to push their narrative, it wouldnt surprise me to eventually see this was constructed to dilute the Roy Moore mess.
When it comes to people like Louis C.K. (whose pattern was established by multiple people) and Weinstein (whose pattern was established by multiple people) and Roy Moore (whose pattern is established by multiple people) and Weiner (who was investigated by the fbi) etc, it is reasonable to call them what they probably are without waiting for a court proceeding.
But right now Bannon needs a narrative to help his guys out of the ditch and this one is _particularly_ convenient combining as it does a vocal member of the resistance and a gay man supposedly drugging and assaulting a victim. Frankly I dont trust sleazy friends of bannon/ daily caller / infowars to not set a vocal progressive up as they are proven to be completely ok with:
A) lying about a witness to Roy Moore getting paid 1000$
B) lying about antifa and the church shooter
C) lying about Muslims involved with steven paddock
D) saying a pedophile is preferable to a liberal Alabama candidate.
They havent earned ANY trust at all on this, and unless there is some well sourced reporting to add meat to this single accusation it seems dumb to just buy it outright. You may do so if you like but if you arent actually a raving cernovich type pizzagate conspiracy lover then you are just naive, pending more info.
In other words, waiting until decent journalism does its job instead of using daily caller and twitter, is still the best place to stay sane and closer to reality.
