The Secret Service on Thursday did not identify the agents or disclose specific grounds for their suspensions.
A gunman opened fire at Trump's rally in Butler, Pennsylvania on July 13, 2024, while the candidate was speaking on stage. The shooter accessed a nearby rooftop with a direct line of sight to the former president.
Trump and others were injured, and a bystander and the shooter were killed. Multiple investigations were launched into the Secret Service, and its director resigned.
Trump said in an interview that will air on Saturday that the Secret Service erred by not stationing an agent on the rooftop and not including local police in the communications system.
"So there were mistakes made. And that shouldn't have happened," he said during an interview with Fox News' My View with Lara Trump.
Secret Service Director Sean Curran, who was the agent in charge of Trump's security detail at the rally, said in a statement: "The agency has taken many steps to ensure such an event can never be repeated in the future."
The Secret Service said it has implemented 21 of 46 recommendations made by congressional oversight bodies. Sixteen other recommendations were in progress and nine were not directed at the Secret Service, it said.
The Secret Service said it was implementing protective measures for golf courses. After the Butler assassination attempt, a man with a gun hid near a Trump-owned golf course in Florida with the intent to kill the then-Republican presidential candidate.
Meanwhile, a man charged with attempting to assassinate Trump in 2024 at his Florida golf course told a federal judge on Thursday he wants to fire his court-appointed lawyers and represent himself.
Ryan Routh made his request during a hearing before US District Court Judge Aileen Cannon.
When the judge asked Routh, 59, whether he wanted her to appoint new attorneys to defend him, Routh replied: "No. I will represent myself."
The US Supreme Court has held that criminal defendants have a right to represent themselves in court proceedings, as long as they can show a judge they are competent to waive their right to be defended by an attorney.
Prosecutors have said Routh methodically plotted to kill Trump for weeks before aiming a rifle through the shrubbery as Trump played golf on September 15, 2024, at his West Palm Beach country club.
A Secret Service agent spotted Routh before Trump came into view. Routh allegedly aimed his rifle at the agent, who opened fire, causing Routh to drop his weapon and flee without firing a shot.
