With the massive scope of the report leaving a lot yet to be learned, here's a guide to the basics of the Mueller report -- from what it is, what to expect and when to expect it:1. What is the Mueller report? Mueller worked under the supervision of the Department of Justice, and he submitted his report to Barr, the head of that department. He also said Mueller's report goes through in detail about whether or not Trump obstructed justice, but the report does not make a final conclusion on the matter either way. Barr will redact, or black-out, some portions of the report in order to comply with a handful of federal laws and internal Justice Department guidelines.
