The Secret Service has admitted that the assassination attempt against former President Donald Trump was a failure of the US Secret Service.

New video obtained CNN shows for the first time the moment a police officer climbed to the top of a building at Donald Trump's July 13 rally and saw the former president's would-be assassin just before the shooting began. Video from a Butler police officer's body-worn camera shows the officer being pulled up to the roof by his colleague and quickly descending after seeing the shooter, Thomas Matthew Crooks. About 40 seconds later, Crooks turned back and fired eight shots at Trump, hitting him in the ear. Seconds later, a Secret Service sniper shot Crooks.

Other footage from the rally in Butler, Pennsylvania, obtained by CNN through a public records request, shows

the local police complain that they told the Secret Service

to station police officers near the building from which the gunman had fired days earlier.

The Secret Service posted three local snipers in an adjacent building, one of whom photographed Crooks that day and then left his post to search for the shooter. In a statement on Thursday, the Secret Service announced that it is reviewing the body camera video that has just been made public.

The U.S. Secret Service appreciates our local law enforcement partners who acted courageously as they worked to locate the shooter that day.”

said Anthony Guglielmi, the agency's spokesman. "The assassination attempt against former President Donald Trump was a failure of the US Secret Service, and we are reviewing and updating our security policies and procedures to ensure that such a tragedy never happens again," he said.
