Some on Mueller’s Team Say Report Was More Damaging Than Barr Revealed

Mr. Barr was also wary of departing from Justice Department practice not to disclose derogatory details in closing an investigation, according to two government officials familiar with Mr. Barr’s thinking. They pointed to the decision by James B. Comey, the former F.B.I. director, to harshly criticize Hillary Clinton in 2016 while announcing that he was recommending no charges in the inquiry into her email practices.

The officials and others interviewed declined to flesh out why some of the special counsel’s investigators viewed their findings as potentially more damaging for the president than Mr. Barr explained, although the report is believed to examine Mr. Trump’s efforts to thwart the investigation. It was unclear how much discussion Mr. Mueller and his investigators had with senior Justice Department officials about how their findings would be made public. It was also unclear how widespread the vexation is among the special counsel team, which included 19 lawyers, about 40 F.B.I. agents and other personnel.

At the same time, Mr. Barr and his advisers have expressed their own frustrations about Mr. Mueller and his team. Mr. Barr and other Justice Department officials believe the special counsel’s investigators fell short of their task by declining to decide whether Mr. Trump illegally obstructed the inquiry, according to the two government officials. After Mr. Mueller made no judgment on the obstruction matter, Mr. Barr stepped in to declare that he himself had cleared Mr. Trump of wrongdoing.

Representatives for the Justice Department and the special counsel declined to comment on Wednesday on views inside both Mr. Mueller’s office and the Justice Department. They pointed to departmental regulations requiring Mr. Mueller to file a confidential report to the attorney general detailing prosecution decisions and to Mr. Barr’s separate vow to send a redacted version of that report to Congress. Under the regulations, Mr. Barr can publicly release as much of the document as he deems appropriate.
