Nearly two years after the shocking shooting that injured Donald Trump during a campaign rally in Butler, Pennsylvania, newly released federal documents are raising fresh questions about what happened before the attack.
At the centre of the controversy are heavily redacted FBI records obtained through a Freedom of Information Act lawsuit, revealing that Butler County officials exchanged emails with alleged gunman Thomas Crooks before the shooting. While the documents do not explain the content of those communications, the discovery has reignited public interest in one of the most scrutinised security failures in recent American political history.
