Attorney General William Barr announced on Friday that he plans to make the special counsel Robert Mueller's final report in the Russia investigation available to Congress and the public by mid-April or sooner.

In a letter to Senate Judiciary Committee Chairman Lindsey Graham and House Judiciary Committee Chairman Jerry Nadler, Barr said he is working with Mueller to release as much of the report as possible to the public.

Barr added that the Justice Department is in the process of redacting the following types of information:

Information that went before a grand jury but did not result in criminal charges

Information that could compromise intelligence sources and methods

Information that could pertain to other ongoing investigative matters

Information that would "unduly infringe on the personal privacy and reputational interests of peripheral third parties."

The attorney general also said in his Friday letter that he would not send Mueller's report to the White House for a privilege review, a reversal of his earlier statement to Graham on the subject. The final report is nearly 400 pages long.

On Sunday, Barr released a four-page review of Mueller's findings regarding election interference in the 2016 election and possible obstruction of justice by President Donald Trump, immediately sparking calls for the full report to be made public.

Barr's review, which listed Mueller's "principal conclusions," said Mueller did not find sufficient evidence to bring a criminal charge of conspiracy against Trump, the campaign, or anyone associated with it.

The review also said Mueller's team did not make a "traditional prosecutorial judgment" as to whether Trump obstructed the Mueller probe itself and other federal investigations involving him.

Barr's letter on Sunday added that while Mueller did not "draw a conclusion — one way or the other — as to whether the examined conduct constitutes obstruction," Mueller's report "also does not exonerate" Trump of any criminal conduct.

Barr continued that he and Deputy Attorney General Rod Rosenstein, who oversaw the Mueller probe for most of its duration, concluded that the special counsel's findings were "not sufficient" to determine that Trump committed obstruction of justice.

In the letter to Graham and Nadler, Barr said is willing to testify about the report before their respective committees in early May.
