A federal judge in Washington refused on Tuesday to fast-track the release of Special Counsel Robert Mueller’s report on the Russia investigation, ruling that a group suing for those records had failed to show that it would be irreparably harmed by a slower disclosure process.

U.S. District Judge Reggie Walton said he appreciated the desire of the Electronic Privacy Information Center to obtain the Mueller report, a document detailing what he described as an “extremely important subject matter to the nation.” But Walton denied the group’s push to have the Justice Department immediately begin the process of fulfilling the Freedom of Information Act request, saying, “I have not been convinced that irreparable harm has been established.”
