Observers in Butler, Pennsylvania, estimate that as many as 100,000 people could attend former President Donald Trump‘s rally at the Butler Farm Show grounds on Saturday, nearly three months after he and several rallygoers were shot there in an attempted assassination.

Local news outlets reported that supporters of the former president camped out at the fairgrounds more than 24 hours before the rally in hopes of being the first ones let into the venue to get a front-row spot.
