Former US president Donald Trump was rushed off stage during a rally in Pennsylvania after a gunman fired multiple rounds from an "elevated position" a few hours ago.
Trump said a bullet pierced the "upper part" of his right ear, in a post on social media.
One person was killed and two others injured according to law enforcement.
The FBI has identified the suspected gunman, who was shot and killed by the Secret Service, as 20-year-old Thomas Matthew Crooks.
At an earlier press conference, FBI field officer Kevin Rojek confirmed that the incident was being treated as an assassination attempt.
Law enforcement officers were pressed on the response time to the gunman. State police said it's "too early" to determine what happened as "everything unfolded very quickly".
State police said they're following up on reports that a witness saw the shooter on the roof.
No matter what you think of Donald Trump this is shocking news to wake up to this morning.
