Redacted Mueller report expected to be released Thursday morning

Those categories include:

• Material subject to Federal Rule of Criminal Procedure (6e) that cannot be made public.
• Material the intelligence community identifies as potentially compromising sensitive sources and methods.

• Information that would unduly infringe on the personal privacy and reputational interests of peripheral third parties.

Barr told a House Appropriations subcommittee that once the redacted version of the report is sent to Congress, he would be "glad to talk to [House Judiciary] chairman Nadler and [Senate Judiciary] chairman Graham as to whether they feel they need more information and see if there’s a way we could accommodate that."

• Barr said that he doesn't believe he has the latitude to release grand jury material and that he doesn't intend to ask a judge to unseal it. He added, however, that Nadler is free to make the request if he wants.
