The President had been talking excitedly for days about the rally, his first since early March, as the 2020 campaign was sidelined by the Coronavirus outbreak.
"It's a crowd like, I guess, nobody has seen before," the President said last Thursday, during an roundtable with the Governor of Oklahoma.
"We have tremendous requests for tickets, like I think probably has never happened politically before," the President added.
As the number of requests for tickets went up all week - finally clearing over 1 million - the Trump Campaign went so far as to build an outside stage, so the President could address those unable to get inside the BOK Center in Tulsa.
But it wasn't needed.
The Trump Campaign denied stories that TikTok users had sabotaged the event by signing up for huge numbers of tickets.
