Barr's testimony offers new clues about what the Mueller report will look like

Barr's comments came at a House subcommittee hearing, where he was peppered with questions about the Russia investigation and a host of other department issues.

Here's a breakdown of what you need to know.

The wait is almost over. Barr said he will release a redacted version of Mueller's report "within a week." He said everything is on track to meet his goal of sending the report to Congress by mid-April, a timeline that he laid out in a letter to lawmakers last month.

There will be redactions. This wasn't groundbreaking. But it demonstrates that Barr is holding steady to his position that there must be redactions in the report. So far, Barr has resisted demands from top Democrats to provide a full, unredacted copy to Congress.

Four types of redactions. The four categories of redactions are: Grand jury material, classified information, details about ongoing investigations, and information that harms "privacy and reputational interests of peripheral third parties."

The report will be colorful. Every redaction will be explained in the public version of Mueller's report. Barr told the subcommittee: "We will color-code the excisions from the report and we will provide explanatory notes describing the basis for each redaction."

Many cooks in the redaction kitchen. Mueller's team is helping Barr black out grand jury material and sensitive information about "peripheral players...who shouldn't be charged," Barr said. The intelligence community is scrubbing the report for national security secrets. And federal prosecutors are redacting details about their ongoing investigations.

No plan for executive privilege. President Donald Trump has previously said he wants the full report to be public. Barr told lawmakers that there was "no plan" for him or anyone else to assert executive privilege over parts of the report, which would trigger further redactions.
