A redacted version of Special Counsel Robert Mueller III’s report on the Russia investigation will be delivered to Congress by mid-April, “if not sooner,” U.S. Attorney General William Barr said Friday in a letter to congressional leaders detailing how he plans to prepare the nearly 400-page document for public release.

With Mueller’s assistance, Barr said the Justice Department is “well along in the process” of reviewing and redacting any grand jury information in the document, along with any information that could interfere with ongoing investigations. Barr said he does not plan to submit the report to the White House for a review by the president’s lawyers.
