US Attorney-General William Barr plans to issue a redacted copy of Special Counsel Robert Mueller's nearly 400-page investigative report into Russian interference in the 2016 election by mid-April.
"Everyone will soon be able to read it on their own," Barr wrote in a letter to the top Democrats and Republicans on the Senate and House Judiciary committees.
Barr said he is willing to appear before both committees to testify about Mueller's report on May 1 and May 2.
Mueller completed his 22-month investigation into whether President Donald Trump's campaign colluded with Russia on March 22.
Barr sent a four-page letter to Congress summarising Mueller's findings on Sunday (US time).
Barr told lawmakers that Mueller's investigation did not establish that members of the Trump campaign conspired with Russia in its election interference activities.
Mueller left unresolved the question of whether Trump obstructed justice during the investigation. Barr said that based on the evidence presented, he concluded it was not sufficient to charge the President with obstruction.

Lawmakers have since been clamouring for more details, with Democrats calling for a full release of the report.
Barr said in his letter on Friday that certain information must be redacted before the report is released, including secret grand jury information, intelligence sources and methods and information that by law cannot be public or might infringe on privacy.
He said that while Trump has the right to assert executive privilege on some materials, that "Trump has stated publicly that he intends to defer to me".
Because of that, Barr said, there are no plans for the Justice Department to submit the report to the White House for a privilege review.
