Which we all know already considering the full report was released.
"When Barr pressed Mueller on whether he thought Barr’s memo to Congress was inaccurate, Mueller said he did not but felt that the media coverage of it was misinterpreting the investigation, officials said."
"“After the Attorney General received Special Counsel Mueller’s letter, he called him to discuss it,” a Justice Department spokeswoman said Tuesday evening. “In a cordial and professional conversation, the Special Counsel emphasized that nothing in the Attorney General’s March 24 letter was inaccurate or misleading. But, he expressed frustration over the lack of context and the resulting media coverage regarding the Special Counsel’s obstruction analysis. They then discussed whether additional context from the report would be helpful and could be quickly released."
