Gaige “Lefty” Grosskreutz was quoted shortly after the shooting stating that he wished he had killed Rittenhouse.
Lefty’s felonious past probably won’t be admissible, but that statement might be, if it can be authenticated (my recollection is that a friend visiting him in the hospital was the one quoted by the media).
Lefty say’s he is not a felon, and I’ve yet to see any arrest or court records.
