A suspected gunman who opened fire during a rally Saturday in Butler, Pennsylvania, for former President Donald Trump is dead, the Butler County District Attorney said.

Butler County District Attorney Richard Goldinger told CBS Pittsburgh that two people are dead — the gunman and an audience member. No further details were immediately provided. 

Law enforcement sources told CBS News that the suspect had been "neutralized."

Several shots rang out while Trump was speaking on stage. The former president immediately touched his ear and crouched to the ground. He was rushed out and the Secret Service later confirmed that he was safe.

This is a developing story and will be updated.
