Did he even say specifically that the shooter was from the maga movement?
I think if you read that in the context of "maga has called the killer everything from a furry, leftist, antifa, tranny, tranny lover, groyper etc, anything but the possibility they are from maga) then it is a factual statement, maga has been convinced who the shooter was from day one despite shifting narratives and spurious evidence that even investigators arent agreeing with, as can be seen in any of the Charlie kirk related threads.
