To hear CNN talk, Mueller is on a rampage. They say Mueller said that Barr misappropreated his concluding points in the report. Actually, here is what Mueller actually said:

From the Wa/Post we have this: 
"When Barr pressed him whether he thought Barr's letter was inaccurate,  Mueller said he did not [think so],  but felt that the media coverage of the letter was misinterpreting the investigation [outcome] 

I wonder how many times this gets  misreported. 

Update:  Turns out that this Wa/Post headline was/is a lie.  The truth is above:
