During a rally in Pennsylvania, former President Donald Trump was quickly whisked away by Secret Service agents after multiple bangs were heard.
The sounds, which appeared to be gunshots, caused commotion among the crowd and prompted immediate security measures.
Trump, seemingly unharmed, was taken to a nearby medical facility for precautionary evaluation, according to his campaign.
The Secret Service has launched an investigation into the incident and the White House has confirmed that President Biden has been briefed on the situation.
