Former President Donald J. Trump was rushed off a stage by Secret Service agents at a rally in Butler, Pa., after several pops that sounded like gunshots.

Mr. Trump went to the ground and was immediately surrounded by agents, who then escorted him to a motorcade. The former president pumped his fist at the crowd as he was hustled off the stage.

When the pops began at 6:13 p.m., Mr. Trump appeared to grab his right ear, which appeared to be bleeding as he left the stage.
