Secret Service’s bombshell admission about Donald Trump assassination attempt

The US Secret Service has admitted multiple failures over the assassination attempt of Donald Trump at a rally in July.

The US Secret Service has detailed a litany of security failures uncovered by its review of the attempted assassination of former president Donald Trump at a rally in July.

Shooter Thomas Matthew Crooks was able to open fire from a nearby rooftop at the outdoor event held by Republican election candidate Mr Trump, who narrowly escaped death and suffered a wound to his right ear.

The review “identified deficiencies in the advanced planning and its implementation by Secret Service personnel,” acting director Ronald Rowe said at a press briefing on Friday, local time.

“While some members of the advance team were very diligent, there was complacency on the part of others that led to a breach of security protocols.”

Among the failures identified by Mr Rowe were poor communication with local law enforcement, an “over-reliance” on mobile devices “resulting in information being siloed” and line of sight issues, which “were acknowledged but not properly mitigated.”

“At approximately 18:10 local time, by a phone call, the Secret Service security room calls the countersniper response agent reporting an individual on the roof of the AGR building,” Mr Rowe said.

“That vital piece of information was not relayed over the Secret Service radio network.”

Two attendees of the rally in Butler, Pennsylvania were injured from gunfire and a third, 50-year-old firefighter Corey Comperatore, died as a result.

Crooks was shot dead by Secret Service personnel.

Secret Service director Kimberly Cheatle resigned in the aftermath of the incident and several additional Secret Service agents have been put on leave.

Mr Trump escaped a second attempted assassination in two months last weekend, with glaring questions being asked about how a gunman was again able to get within a few hundred metres of the former President.

Secret Service shot at a man armed with a scoped AK-47-style rifle on Sunday afternoon after he was spotted pointing the barrel through the chain-link fence at the Trump International Golf Course in Florida, close to Mr Trump’s Mar-a-Lago home.

Mr Trump was 300 to 500 yards (275 to 460 metres) away on the fifth hole when shots rang out at about 1.30pm (3.30am AEST), according to police.

He was quickly rushed to safety and was unharmed.
