On Saturday, a man in Dayton, Ohio, charged through a security barricade toward the stage where Trump was speaking. Trump later tweeted what appeared to be a doctored video purporting to show the protester with a gun and the backdrop of the ISIS flag. Despite evidence to the contrary, Trump accused the protester of links to ISIS.

Donald Trump: “This wasn’t a guy that was looking to, you know, have a little fun. This was a guy that was looking to do harm. So the judge let him go. And then one of my people said, 'Wow!' They found his name, and it was probably ISIS or ISIS-related. Do you believe it? And then they go online—my people found this. Then they go online, and they find the guy is playing all sorts of very—let’s say music that you wouldn’t be liking, dragging an American flag along the sidewalk, making all sorts of gestures, having all sorts of things on the Internet.”

The protester, Thomas DiMassimo, told police he planned to take the stage and say, “Donald Trump is a racist,” in the microphone. Meanwhile, Trump has blamed supporters of Vermont Senator Bernie Sanders for the violence at his rallies. We’ll have more on the unrest after headlines.
