Last Friday, special counsel Robert Mueller delivered his long-awaited report on Russian interference in the 2016 election, possible coordination between Russia and the Trump campaign, and whether President Trump obstructed the investigation. But it remains very unclear how much the public will actually get to read of the most anticipated political document in recent history.

Attorney General William P. Barr and Justice Department staff will have the task of reviewing the Mueller report to determine how much of it contains classified information, grand jury materials, sensitive law enforcement records, and other portions shielded from public release by executive privilege.

The fight over the scope and breadth of the redactions to the public version of the Mueller report will pit privacy, national security, and presidential privilege against the considerable public interest in the Russia investigation. It will play out on two fronts: the Justice Department will face off against Congress, where the House recently voted 420-0 to urge the DOJ to make the Mueller report public; and the DOJ will also have to battle private groups in federal court.
