A “cascade of preventable failures” within the U.S. Secret Service nearly cost President Donald Trump his life during a campaign rally in Pennsylvania last year, according to a Senate committee report released Sunday.

The Republican-led Senate Homeland Security and Governmental Affairs Committee, which oversees the Secret Service, found that a series of lapses in planning, communication and coordination allowed 20-year-old Thomas Matthew Crooks to climb undetected onto a rooftop overlooking the rally in Butler, Pennsylvania, and open fire on July 13, 2024.

“It is a miracle that President Trump survived,” Senator Rand Paul of Kentucky, the committee’s chairman, said in the report. “What happened was inexcusable, and the consequences imposed so far do not reflect the severity of the situation.”

The findings were released on the one-year mark of the shooting, which jolted the 2024 presidential campaign. Trump, who was grazed in the ear, moments later raised his fist and chanted, “Fight, fight” — an image his campaign capitalized on.

According to the Secret Service, six agents were suspended for up to 42 days without pay.

The committee probe, which included 17 interviews and more than 75,000 pages of documents, showed that repeated requests for additional security were either denied or left unfulfilled in the months before.

Numerous questions remain about the shooting, including Crooks’ motivation. Democrats on the committee did not immediately comment on the report.

Agents assigned to Trump’s protective detail told investigators they often refrained from submitting further requests because they were convinced headquarters would deny them, according to the report.

Just 25 minutes before Crooks fired toward Trump, local law enforcement reported a suspicious man carrying a rangefinder outside the rally perimeter. But the Senate report says a Secret Service supervisory agent failed to broadcast the warning over the agency’s radio network, and the message failed to reach agents on Trump’s protective detail.

The report found significant gaps in how agents were briefed. One counter-sniper assigned to the Butler rally testified he had not been told about any intelligence suggesting a potential long-range threat. That agent chose not to report a suspicious person because he assumed someone else would act.

“I’m not the only one that’s observing that area,” the agent told investigators. “Someone else could’ve also put out the radio call.”

Crooks fired eight shots, killing Corey Comperatore, a local firefighter, and wounding two other attendees before he was shot and killed by a Secret Service sniper.

“There were multiple, unacceptable failures in the planning and execution of the July 13 Butler rally,” the committee said in its report.

The committee found that the agency denied “multiple requests for additional staff, assets, and resources to protect President Trump” during the presidential campaign. The committee said that included at least two requests for the Butler rally.

The agency’s former director, Kim Cheatle, last year told a House panel before she resigned that the agency didn’t deny any requests for the rally.

Anthony Cangelosi, a former Secret Service agent who is now a lecturer at John Jay College of Criminal Justice, said that without being able to read the interviews with the agents involved in the Butler planning it’s hard to know exactly why they did what they did. But a year later, he still struggles with how so many things went wrong.

“I can’t understand how many errors were made on that site that day,” he said. “If they agreed to leave that roof unoccupied, I can’t … understand it for the life of me.”

The widow of Corey Comperatore echoed the sentiment during an interview with Fox News this week.

“Why was that such a failure? Why weren’t they paying attention? Why did they think that that roof didn’t need covered? I want to sit down and talk to them,” Helen Comperatore said.

Cangelosi said he thinks the Secret Service needs better pay to retain agents tempted to leave the agency for other federal government jobs.

Retired supervisory agent Bobby McDonald, who’s now a criminal justice lecturer at the University of New Haven, said he suspects part of the problem ahead of the Butler rally was that the Secret Service might have had a hard time understanding that the type of protection Trump needed wasn’t the same as for other former presidents.

He said it “boggles the mind” how Crooks was able to get on that roof and said that “communication” and “complacency” are the two issues that he thinks really went wrong in Butler.

But he also said that he feels the agency is moving in the right direction. “A lot of good people doing a lot good work there,” he said, “and I hope they continue to move in the right direction.”

The agency said Sunday that following the assassination attempt, they took a “serious look” at their operations and have undergone significant reforms to address what happened that day.

“Since President Trump appointed me as director of the United States Secret Service, I have kept my experience on July 13 top of mind, and the agency has taken many steps to ensure such an event can never be repeated in the future,” said Sean Curran, whom Trump tasked with leading the agency. Curran was one of the agents standing next to Trump as he was hustled off the stage after the shooting.

The agency said it had implemented 21 of the 46 recommendations made by Congressional oversight bodies. The rest were either in progress or not up to the agency to implement.
