When the Mueller Report is finished and presented to him, will he release the contents of it to the American people...to Congress..or will he file it away and "tell us" everything is OK, little donny is OK, and everything will continue on as-is. Why would little donny appoint a man with honor and integrity? He hates those people and tries to sabotage undermine vilify and lie about them 24/7. He selects people to service him and him alone. Why should William Barr not be one of them? Place your bets.
