Trump assassination attempt: FBI identifies Pennsylvania rally shooter as Thomas Matthew Crooks, exact motive unknown

Two people have been killed and two remain in a critical condition after a suspected attempt on Donald Trump’s life at a campaign rally in Pennsylvania.

One of the dead is 20-year-old Thomas Matthew Crooks, who the FBI said fired several shots in the former US president’s direction from a rooftop on a property next to the rally.

Mr Trump was also injured in the incident, and could be seen bleeding from the ear as he was rushed from the stage by the Secret Service, pausing to raise a fist in the air as his supporters chanted “USA, USA!”.

The FBI is investigating the shooting, and the Secret Service is facing questions from congressional leaders as to how a man with a rifle was able to get into a position with a clear line of sight to the former president.
