Spokesperson Kerri Kupec said Monday the redacted report will be sent to Congress and made available to the public Thursday. Two days later, Barr summarized Mueller's conclusions in a four-page letter.
Last month, Barr released a four-page summary of Mueller's principal conclusions, which stated that Mueller's investigation did not establish a criminal conspiracy between Trump's team and the Russian government, and Mueller did not reach a conclusion on obstruction of justice, though Barr wrote the investigation did not exonerate Trump.
Democrats also are skeptical of Barr's conclusion because he has always been opposed to the special counsel investigation and was hired by Trump. Attorney General Bill Barr has already reported that Mueller concluded there was no collusion, although reports have suggested the Mueller report presents arguments for and against claims that Trump obstructed justice.
Mueller submitted the document to the attorney general on March 22. Barr also has said he planned to redact material related to intelligence-gathering sources and methods. They've expressed concerns that Barr will redact information that is embarrassing to Trump.
The Justice Department didn't immediately respond to a request for comment.
Stratolaunch, the World's Biggest Aircraft, Makes Historic 1st Flight
The twin-fuselage Stratolaunch jet landed two hours after taking off from Mojave Air and Space Port in California . While Stratolaunch calls its aircraft the world's largest, other airplanes exceed it in length from nose to tail.
The redactions in the report will be colour-coded by category, according to Barr, explaining the reasons that parts are blacked out.
As a Trump appointee, Barr has been under pressure from Democrats to release the report without redactions. Last week, Barr told a U.S. Senate panel he believed that "spying" did occur on Trump's campaign, and he plans to investigate whether it was properly authorized.
"In other words, (Barr) thinks as a matter of law a president can't obstruct justice, which is a very wild theory to which most people do not agree", Nadler said.
"I have said, and I'll say again, 'No thank you, Mr. Attorney General".
One mystery is what, if anything, came of the special counsel's questioning of George Nader, a Lebanese-American businessman and consultant to the crown princes of the United Arab Emirates and Saudi Arabia who started cooperating with Mueller previous year.
