What I noticed first was that Sullivan takes a shot at Flynn's attorney, Sidney Powell, suggesting that she has engaged in "professional misconduct" for plagiarization, by "merely provid[ing] a hyperlink" to a brief she quotes rather than a direct citation (p. 17):
I dunno. Sullivan's language strikes me as a bit over the top, a bit of a cheap shot, in that Powell was hiding nothing (any more than Flynn hid anything from the FBI)--what she did doesn't appear to be "dishonesty, fraud, deceit, or misrepresentation”, even if it wasn't in full compliance with the rules.
And that was before additional details on the cheapness, even idiocy, of Sullivan's comments came out (quoting Techno Fog and Turley). What we see is a pattern of what DC law professor Jonathan Turley went so far as to call "false allegations" on the part of Sullivan.
So now Mirengoff goes there, too--plainly stating that "Sullivan’s accusation ... smacks of personal hostility."
You have to wonder whether this all may have some effect down the road.
