“The Secret Service has implemented protective measures and the former president is safe,” a Secret Service spokesperson said on X after what the agency called an incident.

“This is now an active Secret Service investigation and further information will be released when available.”

Multiple shots were heard at the outdoor rally in Butler, Pennsylvania, shortly after Trump began his speech.

Body guards then crowded around the former president as he ducked below the podium and armed officers took up positions at the front of the stage.

CNN reported that Trump was injured, but gave no other details. It was not clear how or what injuries he may have sustained. Video showed him with blood on his right ear and the right side of his face.

Trump repeatedly raised his fist to the crowd and shouted as he was escorted to a vehicle by the US Secret Service.

Trump’s campaign spokesperson said Trump was fine and that he was being checked out at a local medical facility, according to a CNN reporter on X.

The venue was abandoned with chairs knocked over and yellow police tape around the stage. A helicopter flew above and law enforcement officers walked through the area, the video feed showed. Armed law enforcement officers were also seen on a roof near the stage where Trump was standing.

US President Joe Biden received and initial briefing on the incident, the White House said.

Trump and Biden are locked in a close election rematch, with most opinion polls including Reuters/Ipsos showing the two evenly matched.

Trump, who served as president from 2017-2021, easily bested his rivals for the Republican nomination early in the campaign and has largely unified around him the party that had briefly wavered in support after his supporters attacked the US Capitol on January 6, 2021, attempting to overturn his 2020 election defeat.
