The Justice Department announced Monday that it expects to release the redacted version Thursday morning, sending the findings of the almost two-year probe to Congress and making them available to the public. However, you won't be able to read all of it.
No one other than Barr and key officials in the Justice Department, Mueller and his team of prosecutors appear to know what the report says about the extent of Trump campaign links with Russian Federation during his 2016 campaign or whether he took any actions as the US leader aimed at inhibiting the investigation.
Mr. Trump is scheduled to meet with Secretary of State Mike Pompeo and participate in a Wounded Warrior Project Soldier Ride the day Barr is expected to release Mueller's redacted report.
On Twitter, Trump said last Saturday, "Why should Radical Left Democrats in Congress have a right to retry and examine the $35,000,000 (two years in the making) No Collusion Mueller Report".
He's told the parties in court he's interested in putting the proceedings on a "fast track", he said Tuesday. In the letter, which was obtained by The Associated Press, Schiff and Nunes also asked for a private briefing from Mueller and his team. "They're going to be looking for anything in there, and certainly I think Thursday's kind of all upside for them because in their estimation anything that doesn't say no collusion, no obstruction is probably - good news".
Barr has said he will release as much of the Mueller report as possible, while excluding material Mueller included from secret grand jury testimony and confidential US intelligence sources, information about ongoing investigations and material that might prove damaging to peripheral figures in the investigation who have not been charged with criminal offenses. Those include cases handed off or referred to federal prosecutors in Washington, New York and Virginia.
Democrats have noted that the Justice Department has released such information before, including some related to Mr Mueller's own investigation while it was in progress.
Mr. Trump, meanwhile, is trying to keep the public focused on Mr. Mueller's bigger conclusion that there was no criminal conspiracy with Russian Federation - undercutting the narrative that launched the lengthy investigation.
Republicans argued at the time that it was necessary to obtain that information to maintain the integrity of the investigation.
The Justice Department regularly redacts information about people who were interviewed or scrutinized in investigations but not charged. But any information regarding his sons, Eric and Donald Trump Jr., who run his businesses, could be more likely to be redacted. Barr signaled in his confirmation hearing in January that he would do things differently.
"If you're not going to indict someone, then you don't stand up there and unload negative information about the person", Mr Barr said.
Fearing retribution from an angry president, some of those presidential confidants have been reaching out to the Justice Department to see whether they will be named as collaborators in Mr. Mueller's findings.
