Mueller speaks up for the first time, slams Attorney General for misrepresenting his report

Just days after Attorney General William Barr announced his summary conclusion's of Special Counsel Robert Mueller's report, Mueller wrote a letter to the Justice Department expressing his extreme dissatisfaction.

The contents of that letter are becoming public for the first time ever, just hours before Barr is set to testify before Congress on Wednesday morning. That is, if he shows up.

Barr said he might not even go. Congress said they'd subpoena him. So, right now, if he doesn't appear, that's exactly what will happen.

In any case, right now, as it stands, Mueller isn't happy with Barr's summaries or conclusions of his report, and he put that all in writing. Congress will attempt to get to the bottom of Barr's communications with Mueller in full. He isn't ready for that, because it all paints him and President Trump in a bad light.

Here's what we know so far: Mueller is accusing Barr of "not fully capturing the context, nature, and substance" of his work. Wow. That was pretty harsh. Mueller made Barr call him and talk for at least 15 minutes after he read his private letter. Expect that call to come up should Barr testify on Wednesday.

A full copy of the letter currently rests with the Washington Post, and they haven't released it in full, yet. But, these are the main takeaways.

Mueller also wrote:

"There is now public confusion about critical aspects of the results of our investigation. This threatens to undermine a central purpose for which the Department appointed the Special Counsel: to assure full public confidence in the outcome of the investigations."

Mueller also made a key request of Barr, to fully release the 448-page report's introductions and executive summaries, and made some initial reactions for doing so.

Mueller was in disagreement about Barr's delaying the release of the report, too, saying that it wasn't necessary and that the public had a right to see its contents right away.

Mueller also took issue with Barr's "summary," saying Barr's key conclusions did no such thing.

Now - the latest development - has House Judiciary Chairman Nadler demanding the letter. We could have predicted this would happen.

It's possible that even Mueller himself could testify soon.
