They can definitively state that he was found guilty for his hand in the insurrection, as per the multiple cases. There’s no room for libel there, it’s a fact. He was found guilty.

Did I miss a case? AFAIK, to date he hasn’t been found guilty of anything because that would imply he’s been through a criminal trial to completion and we should be talking about his sentencing.

To the best of my knowledge he’s been found liable in a couple of civil cases and owes a buttload of damages as a consequence, but still hasn’t been found guilty of any crime, yet.
