The Buzz Feed false story

We have learned that at about 7:30 pm, Mueller stated that the recent Buzz Feed story was false and not accurate.  It took the Mueller's team over 24 hours to make this statement and why was that?  Because he knew that William Barr was and will be the next Attorney General, A real Attorney General, who would rip Mueller a new asshole if he did not deny this phony story that may have come from someone on his investigation team that has been leaking false stories to the news media to get the media go on their wild witch hunt on getting Trump impeached.  Something they have been doing for past two years with false stories.  So, we can expect William Barr to start out running, unlike Sessions who went into hiding and realized he was in over his head and would not address phony stories.  Rod Rosenstein had better beware that he may be in the crosshairs as he got Mueller installed as Special Council while he was involved in the FISA warrant false affidavit presented to the court in addition to two present members of the Mueller team.  This could be Mueller moving towards self preservation.
