The Secret Service says there was no weapon involved in the commotion that briefly disrupted Donald Trump's rally in Reno, Nevada, and caused agents to hustle Trump from the stage.
The Republican nominee had been speaking to supporters for a while when a disturbance broke out in the crowd close to the podium. Two Secret Service agents quickly surrounded Trump, then hustled him off the stage.
In a statement, the Secret Service said a person in front of the stage had shouted "Gun!" but that no weapon was found after a search of the person and the immediate area. The person was apprehended, but officials did not identify the person or disclose whether he had been charged with a crime.
The Secret Service said an investigation into the incident was ongoing.
