MSNBC did one article way back (before the
integrity of the DNC was revealed) about the feuding primary campaigns. And the above Lifezette article got play on the Fox-Nation website few days ago. Primary ref I could find appropriate to when it was actually filed was a July 2016 article announcing it by RT, you know the propaganda arm of the guy that gave Trump the White House.
FTR, it is:
WILDING ET AL. V. DNC SERVICES CORPORATION, ET AL. Case No. 16-cv-61511
Federal Court of the Southern District of Florida
Dear Plaintiffs, think really big numbers please.
