Robert Mueller isn't happy

Special counsel Robert S. Mueller III wrote a letter in late March complaining to Attorney General William P. Barr that a four-page memo to Congress describing the principal conclusions of the investigation into President Trump “did not fully capture the context, nature, and substance” of Mueller’s work, according to a copy of the letter reviewed Tuesday by The Washington Post.

At the time the letter was sent on March 27, Barr had announced that Mueller had not found a conspiracy between the Trump campaign and Russian officials seeking to interfere in the 2016 presidential election. Barr also said Mueller had not reached a conclusion about whether Trump had tried to obstruct justice, but Barr reviewed the evidence and found it insufficient to support such a charge.

Days after Barr’s announcement , Mueller wrote a previously unknown private letter to the Justice Department, which revealed a degree of dissatisfaction with the public discussion of Mueller’s work that shocked senior Justice Department officials, according to people familiar with the discussions.

“The summary letter the Department sent to Congress and released to the public late in the afternoon of March 24 did not fully capture the context, nature, and substance of this office’s work and conclusions,” Mueller wrote. “There is now public confusion about critical aspects of the results of our investigation. This threatens to undermine a central purpose for which the Department appointed the Special Counsel: to assure full public confidence in the outcome of the investigations.”

The letter made a key request: that Barr release the 448-page report’s introductions and executive summaries, and made some initial suggested redactions for doing so, according to Justice Department officials.

Justice Department officials said Tuesday they were taken aback by the tone of Mueller’s letter, and it came as a surprise to them that he had such concerns. Until they received the letter, they believed Mueller was in agreement with them on the process of reviewing the report and redacting certain types of information, a process that took several weeks. Barr has testified to Congress previously that Mueller declined the opportunity to review his four-page letter to lawmakers that distilled the essence of the special counsel’s findings.

In his letter, Mueller wrote that the redaction process “need not delay release of the enclosed materials. Release at this time would alleviate the misunderstandings that have arisen and would answer congressional and public questions about the nature and outcome of our investigation.”

Barr is scheduled to appear Wednesday morning before the Senate Judiciary Committee — a much-anticipated public confrontation between the nation’s top law enforcement official and Democratic lawmakers, where he is likely to be questioned at length about his interactions with Mueller.

A day after the letter was sent, Barr and Mueller spoke by phone for about 15 minutes, according to law enforcement officials.

In that call, Mueller said he was concerned that news coverage of the obstruction investigation was misguided and creating public misunderstandings about the office’s work, according to Justice Department officials.

When Barr pressed him whether he thought Barr’s letter was inaccurate, Mueller said he did not, but felt that the media coverage of the letter was misinterpreting the investigation, officials said.

In their call, Barr also took issue with Mueller calling his letter a “summary,” saying he had never meant his letter to summarize the voluminous report, but instead provide an account of the top conclusions, officials said.

Justice Department officials said in some ways, the phone conversation was more cordial than the letter that preceded it, but they did express some differences of opinion about how to proceed.

Barr said he did not want to put out pieces of the report, but rather issue it all at once with redactions, and didn’t want to change course now, according to officials.

Throughout the conversation, Mueller’s main worry was that the public was not getting an accurate understanding of the obstruction investigation, officials said.
