Another theory that may hold water.
Possible. Or its a long-term play by bad actors to embed this Kate into the QAnon community and establish her as its Face (i.e. Ocasio-Cortez -> Democrat/Socialist Party Face).
Then put Kate on the talkshow circuit where she could proceed to embarass, discredit, disinform, and completely undermine the entire movement.
Ok it gets even stranger. You know that newspaper article she was carrying around at the rally?
Well it has disappeared and the guy who supposedly wrote it - well his whole website is now gone.
I should have someone here to talk to or at least to tell me to knock off reading 8chan. Alas I am now talking to myself, that is probably not a good thing.
Kate was the name on the diet coke Peter Strozk was drinking at his testimony. Message?
Serial Brain got it wrong, if so...
