FBI reveals new details about Trump shooter (PHOTOS)

The would-be assassin’s motive remains a mystery, US authorities have said

The Pennsylvania man who tried to kill Republican presidential candidate Donald Trump most likely worked alone, the FBI has said, adding that his motive remains a mystery.

Thomas Crooks fired eight shots at Trump during a rally in Butler, Pennsylvania last month, nicking the candidate’s ear, killing one member of the audience and injuring two more before he was fatally shot by the Secret Service.
