US Attorney General William Barr sent a letter Friday to Senate Judiciary Committee Chair Lindsey Graham (R – SC) and House Judiciary Committee Chair Jerry Nadler (D – NY) with an update on the Mueller report.

The letter acts to clarify the Attorney General’s summary letter released earlier this week. The new letter highlights that the Department of Justice is working diligently with Special Counsel Robert Mueller to prepare the full report for public release. The Attorney General notes that material is only being redacted on four grounds: federal law, intelligence community requests, material related to other ongoing proceedings, and material which would unduly infringe the privacy of third parties. The Attorney General expects the full report to be ready for release by mid-April if not sooner and explains that the only reason for the delay is the report’s length, which he describes as “nearly 400 pages long (exclusive of tables and appendices).” The Attorney General also agrees to testify before the Senate and House Judiciary Committees on May 1 and 2, after the full report has been released to Congress and the public.

The Attorney General’s initial letter received a mixed response as it both signaled an end to the investigation with no further indictments and revealed that the Mueller report left some legal questions open-ended. The Attorney General notes in the new letter that President Trump had the option to redact information via executive privilege but President Trump has stated he intends to defer to the Attorney General and will waive executive review.
