Just one shooter. 1st volley was the criminal the rest were our guys. 223’s by shooter and sounded like 308’s that killed. Salena Zito was right in front of Trump. Knows guns. Said two different calibers.
I think he got six shots off, in two groups of three. But I'm not 100% about that. It is somewhat possible the second grouping came from someone else, like law enforcement, but I doubt it.
