The Department of Justice plans to release a redacted version of special counsel Robert Mueller’s report to Congress and the public on Thursday, according to Department of Justice spokeswoman Kerri Kupec.

The report on Mueller’s 22-month investigation is nearly 400 pages long. It’s expected to describe the legal analysis and factual findings that support the conclusions previously shared by Attorney General William Barr in a four-page summary of the report last month.

The redacted information includes grand jury material, foreign intelligence that could compromise sources and methods, information about ongoing investigations, and derogatory information about people who were not charged.

According to Barr, Mueller concluded the Trump campaign did not collude with Russia to win the 2016 presidential election. Mueller did not establish whether or not Trump obstructed justice, but Barr said he and Deputy Attorney General Rod Rosenstein concluded there was insufficient evidence to charge the president with obstruction.

The redacted report will be heavily scrutinized by Republicans, who have claimed the report vindicates Trump, and Democrats, who have accused Barr of giving cover to the president.
