"Nothing related to Epstein will come out of Mueller testifying in front of congress on the 24th."

You are correct. What you don't understand is that Mueller's investigation was a "distraction" meant to lead people away from what is really going on. Mueller's investigation was meant to help maintain power by attempting to maintain the illusion so people cannot see or find the truth and it has nothing to do with Trump other than to attempt to re-direct the focus onto him rather than the true evil and those involved.
