My guess is he is trying to deflect coverage away from the upcoming Mueller testimony and Epstein hearing.
#fakenews already knows Mueller's testimony will be a big nothingburger so they would have otherwise spent this week spinning up their false narratives that although Mueller's testimony won't implicate Trump, Trump is still guilty of #orangemanbad stuff
Meanwhile #fakenews has been in damage control mode over the Epstein case
So now the #fakenews is focused on Trump v Pelosi vs AoC & Crew. That will all come to a sudden halt once Mueller raises his right hand. Rather than expecting an outcome based on a weeks worth of #RussiaRussiaRussia #orangemanbad #resist, people will see Mueller's testimony as a non-event.
Followed a day or so later by the details of Epstein's hearing and the possible naming of names. Maybe even some of everyone's "faves"...
