The "History Tour" was announced in June and has featured onstage conversations between Trump and O'Reilly, the former host of Fox News' O'Reilly Factor who was fired by the network in 2017 after a series of sexual harassment allegations. Shortly after the tour was announced, Politico published a story noting organizers were having trouble selling tickets for events, leading to O'Reilly threatening to sue the reporter who wrote the story. During and leading up to his presidency, Trump often showed an infatuation with the large crowd size of his events, regularly belittling opponents whose rallies failed to attract as many supporters. Trump's rallies, however, have been free events.
