The Secret Service has attributed its failure to prevent the Trump assassination attempt to poor planning and complacency.

• The near-assassination of former President Donald Trump at a July campaign rally was the fault of the U.S. Secret Service, according to the agency.
• Some of Secret Service agents displayed "complacency," and there were communication gaps with local police, according to acting Director Ronald Rowe.
• At a July 13 presidential campaign rally in Butler, Pennsylvania, Trump was shot by assassin Thomas Crooks.

The Secret Service admitted on Friday that they were responsible for the failed assassination attempt on former President Trump at a July rally, citing "complacency" among some of their agents and poor communication with local police.

Ronald Rowe, the acting director of the United States Secret Service, stated at a press conference that this was a failure on the part of the agency.

Since the July 13 shooting, the agency has publicly disclosed the internal breakdowns that led to the attack, resulting in the death of a member of the audience.

The security plan at the presidential campaign rally near Butler, Pennsylvania, was primarily the responsibility of the Secret Service. Despite their efforts, assassin Thomas Crooks was able to fire at Trump before being killed.

Rowe stated that the agency failed to provide clear instructions to local law enforcement partners and there were communication gaps among law enforcement personnel on site.

During a rally, a bullet grazed Trump's ear, and two other attendees were critically injured.

The Republican nominee's rally site had known line-of-sight issues, but they were not adequately addressed beforehand.

Although some members of the advance team were very diligent, there was complacency among others that resulted in a security breach with regard to accountability.

Those employees will be held accountable, Rowe said.

On July 23, 10 days after the assassination attempt, former Director Kimberly Cheatle resigned from the Secret Service, and Rowe assumed the role of Director.

Another assassination attempt against Trump occurred at his golf club in West Palm Beach, Florida on Sunday, and the FBI is currently investigating the incident.

On that day, a Secret Service agent opened fire after spotting an apparent rifle poking through a tree line on the edge of the golf course. Later that day, a suspect, 58-year-old Ryan Wesley Routh, was arrested and subsequently charged with two federal gun crimes.

In his remarks on Friday, Rowe emphasized the need for a "paradigm shift" in the Secret Service's operations to address the "evolving" threat level, citing the golf club incident as an example.
