Limited information Barr has shared about Russia investigation frustrated some on Mueller's team
...There was immediate displeasure from the team when they saw how the attorney general had characterized their work instead, according to one U.S. official briefed on the matter.
Summaries were prepared for different sections of the report, with a view that they could made public, the official said.
The report was prepared so that the front matter from each section could have been released immediately or very quickly, the official said. It was done in a way that minimum redactions, if any, would have been necessary, and the work would have spoken for itself.
Muellers team assumed the information was going to be made available to the public, the official said, and so they prepared their summaries to be shared in their own words and not in the attorney generals summary of their work, as turned out to be the case.
