Donald Trump, a candidate for the 2016 Republican presidential nomination, spoke at a campaign rally ahead of the March 15, 2016, Ohio primary. He talked about his cancellation of a rally scheduled for the previous evening in Chicago due to security concerns and accused some of the protesters at his events of being supporters of Democratic candidate Senator Bernie Sanders (I-VT). Later Secret Service agents surrounded Mr. Trump as they escorted someone out who had attempted to rush the stage. Mr. Trump exited from his plane into an open hanger at Wright Bros. Aero at the Dayton International Airport to speak to the crowd gathered there.
