At a rally in Pennsylvania, gunshots were reportedly fired at former U.S. President Donald Trump, prompting security staff to rush him off stage.
Trump appeared to fall and was quickly surrounded by armed guards, staying down for about a minute.
He then stood up, raised his fist, and was escorted to a vehicle, which drove him away. Video footage seemed to show blood on his ear, and he was seen clutching his head.
Trump was taken to a medical facility and is "doing fine," according to his spokesperson Steven Cheung.
The shooter was confirmed dead, killed by Secret Service agents. Details are still unfolding, and the shooting is being investigated as a possible assassination attempt. The shooter was not an attendee at Trump's rally.
An audience member was killed, and another spectator was seriously injured.
U.S. President Joe Biden, speaking to reporters, said he had not been briefed on the incident.
