 A few hours ago, we got a bit more detail about the shooter. He is Matthew Crooks. He's 20, from Bethel Park, which is about an hour's drive away from where this happened. But we don't know the key thing, which was why he was involved in this. The Republican team say that President Trump is doing very well. He's received treatment. He's travelled back to New Jersey. And there's been a huge reaction, as you can imagine, to this shocking incident.
