So, why are social media personalities in front of a congressional committee over consulting work?
It wasn't over the "consulting work" obviously, why would the Republicans want that out there when the best these two can do is lie about it.
The Republicans brought them in because Diamond and Silk claim "Facebook is censoring them"... with zero evidence obviously but given all the Facebook - Cambridge Analytica - Trump campaign stuff, this was an effort to make the Facebook backlash narrative about "leftist Facebook censors conservative voices."
See:
I heard them on Sean Hannity saying that Facebook had censored their page. I immediately checked and, shockingly, no they hadn't.
The amount of time and effort conservatives put into playing the victim has really gone into overdrive now that they control all the elected parts of the federal government
