BREAKING: Secret Service agents placed on leave after Trump assassination attempt: report

The outlet reported that three sources say several members of the USSS Pittsburgh Field Office have been placed on leave following the shooting. As these agents are placed on leave, others have taken their place to fill in as needed for the job.

Administrative leave occurs when a government employee leaves their position on a temporary basis for an investigation or other concern. Former USSS Director Kimberly Cheatle resigned following the shooting at the Butler rally, where Thomas Matthew Crooks was able to evade security, get on top of a roof, and take several shots at Trump as well as the crowd. Acting USSS Director Ronald Rowe has taken on Cheatle's role in the agency.

Although Crooks missed the fatal shot against Trump, striking only the GOP nominee’s ear, audience members were hit, with Corey Comperatore being fatally wounded as he shielded his wife and daughters from the spray of bullets. Two other men were critically wounded, but survived.

Weeks ago, Rowe was grilled in by members of the Senate in a hearing on the failures of the USSS at the time of the rally. When Sen. Josh Hawley (R-MO) inquired about if any agents had been relieved of duty, Rowe responded that he would “not rush to judgment” but that “people will be held accountable” for the security failures.

Rowe stated in his opening remarks, "I went to the roof of the AGR building where the assailant fired shots and laid in a prone position to evaluate his line of sight. What I saw made me ashamed. As a career law enforcement officer, and a 25-year veteran with the Secret Service, I cannot defend why that roof was not better secured."

Rowe told the senators that the assassination attempt was a "failure of imagination," adding, "a failure to imagine that we actually do live in a very dangerous world where people do actually want to do harm to our protectees."

"I think it was a failure to challenge our own assumptions, the assumptions that we know our partners are going to do everything they can, and they do this every day," he remarked at the July 30 hearing.
