Trump survives assassination attempt; FBI identifies shooter.

Donald Trump survived an assassination attempt Saturday night after a shooter opened fire at his campaign rally near Butler, Pennsylvania.

Trump was injured in the attack and was quickly rushed offstage, but soon after declared in a statement he was "fine." The suspected shooter was killed, as was a rally attendee. Two other attendees were critically injured, according to the Secret Service.

Authorities identified the shooter as Thomas Matthew Crooks, 20, but said they have yet to establish a motive for the shooting. The FBI and Pennsylvania state law enforcement officials said they are working together on what they called an active investigation.
