He may have to change that policy in view of the riots and the looting and arson from Antifa/BLM.
The Trump campaign is going to have to do a heck of a lot more pre screening. Everyone who reserves a ticket will have to go through a screening by the Secret Service and put through the GOP database etc.
These are not normal times.
You cannot “RESERVE” a ticket for a Trump rally.
I read a post by someone that was there and they said some of the screeners that were to take temps, etc., left their posts so people could not get screened. There were other factors preventing people from getting in the arena.
