Which is probably why he had to duck and cover behind four secret service members at his own rally in Dayton, Ohio, on Saturday.
An unidentified man allegedly tried to jump a barricade near the stage at about noon, a Department of Homeland Security spokesperson said. He was arrested by Dayton Police and charged with disorderly conduct and inducing panic, both misdemeanors.
But hey, Trump had it covered.
"Thank you for the warning," he said to the crowd. "I was ready for 'em, but it's much easier if the cops do it, don't we agree?"
He later claimed on Twitter that the man had ties to the Islamic State group.
The incident comes just a day after the real estate mogul's rally in Chicago was canceled due to security concerns. A battle royale between his supporters and protesters broke out when the cancellation was announced, leading to arrests and injuries.
Trump later told Fox News, "I am a unifier."
But there's plenty of evidence to suggest that the reality TV star seeks to incite violence at his rallies.
