New bodycam footage of police reaction to Donald Trump assassination attempt

One clip shows local officers getting angry with the Secret Service for not being on the roof in the first place.

"I f***ing told them they needed to post the guys f***ing over here. I told them that, the f***ing secret service," says a Butler Township officer in the moments after the attack.

"I told them that f***ing Tuesday," he adds. The assassination attempt happened at a campaign rally on Saturday 13 July, four days after he says he told officers to cover the roof.

Thomas Crooks shot at Mr Trump, clipping his ear and killing crowd member Corey Comperatore at the rally near Butler, Pennsylvania.

He positioned himself on a roof in a complex next to the Butler Farm Show, where Mr Trump was giving his speech.

Crooks was roughly 135 metres from Mr Trump and outside the safety perimeter set by the Secret Service.

'Dude, he turned around on me'

In the minutes leading up to the attack, the bodycam footage shows an officer being hoisted onto the roof before he spots Thomas Crooks and drops back down, running to his car to grab his gun.

"F***ing this close, bro," he tells another officer, "Dude, he turned around on me."

The officers are then heard shouting to Secret Service agents about which roof Crooks is on.

"This building, he was on top of this building, the left one," one of them is heard shouting.

By the time the officer gets back on the roof, Crooks has been killed by a sniper.

The officer can be heard asking the Secret Service what had gone wrong.

"Before you motherf***ers came out here, I put my head up here like a f***ing idiot by myself, dude…"

"I was f***ing calling out, bro," he says, "F***ing on top of the roof, f***ing… were you not on the same frequency?"

'A US Secret Service failure'

A Secret Service spokesperson said the agency is reviewing the video.

"The US Secret Service appreciates our local law enforcement partners, who acted courageously as they worked to locate the shooter that day," Anthony Guglielmi said in a statement to Sky's US partner NBC News.

"The attempted assassination of former President Donald Trump was a US Secret Service failure, and we are reviewing and updating our protective policies and procedures in order to ensure a tragedy like this never occurs again."

The head of the Secret Service, Kimberly Cheatle, stepped down over the agency's handling of the situation.

The agency's new acting head also told a Senate committee hearing that Secret Service agents could be fired if it is found they broke protocol that day.
