Republican presidential candidate Donald Trump canceled one of his signature rallies on Friday, calling off the event due to safety concerns after protesters packed the arena where he was scheduled to speak. The announcement the billionaire businessman would postpone the rally led a large portion of the crowd inside the University of Illinois at Chicago Pavilion to break out into raucous cheers. Many rushed onto the floor, jumping up and down with their arms up in the air.
