The Senate and House Judiciary Committees have officially been notified that the William Barr received the Mueller report. He notified them that neither the Acting Attorney General nor he vetoed any prosecutorial decision.
He told the Chairs and Ranking Members he may be able to inform them of the main jist of the report this weekend. And he will work with Mueller and Rod Rosenstein on how much else can be released.
Update: DOJ is now saying that there are no outstanding indictments, and no more expected.
