He compared it to offering a verdict in a trial, with the transcript of the proceedings (the Mueller report) to come out later. ("We were not trying to summarize the report," Barr told the Judiciary committee on Wednesday.) Firing Mueller would eliminate the special counsel while removing Mueller for cause would ensure a new individual would be named to carry on the special counsel investigation. One more thing: In May 2017, the Department of Justice made clear that Mueller had no ethical conflicts and was perfectly capable of overseeing the special counsel investigation. All of that is VERY different than how Trump himself has described the findings of the Mueller report and what Barr decided after reading it.
