Story highlights The "Silent Majority" Donald Trump has inspired and rallied throughout his campaign congregated in a riverfront park

The real headliner, though, was Alex Jones

Cleveland (CNN) The "Silent Majority" Donald Trump has inspired and rallied throughout his campaign congregated in a riverfront park here Monday -- a hodgepodge of supporters who, while unlikely to step foot inside the convention hall less than a mile away, nevertheless counted themselves among the real estate mogul's most fervent backers.

Nowhere else to turn, he eventually jumped on stage and bellowed, "Hillary for prison!" Those same words appeared on T-shirts sold by Infowars and, in the days before the airspace over Cleveland was closed, a plane that flew a banner asking for the same.

"If a meme isn't true, it's really hard to get it going. But when something's true, it's easy to get it going. Like 'Crooked Hillary' and 'Hillary for Prison!'"

Bush's political guru. Rove, who Jones confronted at the airport gate with a camera and some "questions" about his role in the "globalist" agenda, had very publicly but unsuccessfully tried to sic security on the blaring conspiracy theorist.
