BOMBSHELL: Secret Service, Police Tracked Suspect for Half Hour Before Trump Assassination Attempt

"No one had warned Trump."

Thomas Matthew Crooks, the 20-year-old gunman who attempted to assassinate former President Donald Trump at a campaign rally in Butler, Pennsylvania, was spotted on the roof 26 minutes before the shooting occurred.

The FBI has confirmed that Crooks was seen by Beaver County emergency services personnel* on the roof of a building with a clear sightline to the former president.

Despite being alerted to his presence, authorities failed to confront him, allowing him to remain hidden for nearly 30 minutes before he opened fire on Trump and the crowd.

There were several onlookers at the Trump rally who spotted the suspect on the rooftop of a building prior to the assassination attempt.

The shocking new allegations have raised questions about how Crooks was able to evade detection and carry out the attack, which left Trump wounded and a member of the crowd dead.
