A Secret Service agent involved in planning security for the 2024 rally where President Donald Trump was nearly assassinated has been suspended and is under internal investigation, according to multiple sources. The inquiry centers on whether the agent failed to properly disclose a relationship and subsequent marriage to a foreign national.
The agent, Myosoty “Miyo” Perez, served as the “site agent” for the Butler, Pa., rally where a gunman grazed Trump’s ear, killed retired firefighter Corey Comperatore, and injured two others. A site agent is responsible for developing and executing security plans for major events attended by current or former presidents and other high-ranking officials, Susan Crabtree for RealClearPolitics reported.
Perez has now been suspended three times in roughly 18 months, according to sources familiar with the matter. She had previously been reassigned from protective duties but was recently allowed to assist in a security role in Miami despite that understanding.
Congressional investigations into the Butler rally faulted Perez for failing to position security personnel on top of the American Glass Building, where the shooter fired his weapon. However, investigators also questioned why an agent with limited experience was placed in charge of security for a large outdoor event.
Sources said Perez married a Brazilian national in April 2025 but did not inform the agency until January. According to public records and individuals familiar with the timeline, the Secret Service issued a suspension and an internal “Do Not Admit” notice after learning of the marriage.
Investigators are also examining whether the individual Perez married had overstayed a visa and was facing a deportation order. Neither the Secret Service nor the Department of Homeland Security responded to requests for comment, and Perez’s attorney said it was “premature to comment.”
The investigation is part of a broader review by the Department of Homeland Security’s Office of Inspector General into the Secret Service’s handling of two assassination attempts against Trump. Sources said multiple reports are in the final stages but have been delayed in part by funding issues.
Internal questions focus on whether Perez followed the required protocols for reporting foreign contacts and major life changes. Federal rules require security clearance holders to disclose such relationships promptly, and failure to do so can result in suspension or revocation of clearance.
Perez reportedly notified the agency of a foreign contact in 2024 but may not have updated officials as the relationship progressed. Sources said investigators are examining whether she accurately reported when the relationship became serious, including cohabitation and marriage.
Former Secret Service officials said the situation raises broader concerns about insider threats and judgment within the agency. “How does a Secret Service agent not properly report a relationship with a foreign national that could be an illegal alien?” former official Rich Staropoli said.
The case has also renewed scrutiny of past incidents involving agents and foreign nationals. Previous cases have included a 2012 investigation into an agent’s undisclosed relationship abroad and a separate case involving a suspected Russian spy working within the U.S. embassy in Moscow.
Sources also pointed to more recent incidents, including a case in Peru involving a Secret Service agent accused of misconduct with foreign nationals. Intelligence officials have warned in recent years about potential foreign infiltration risks within agencies responsible for protecting senior officials.
Perez had already faced discipline for her role in the Butler security failures, including a suspension without pay alongside several other agents. Sources said she had also been disciplined previously for speaking to a reporter without authorization.
Despite those issues, Perez was recently observed assisting in protective operations during a visit by former President George W. Bush in Miami. A social media post highlighting her participation was later removed, according to sources familiar with the situation.
Congressional findings concluded that multiple supervisors signed off on the Butler security plan without identifying critical vulnerabilities. Those supervisors were not disciplined and later received promotions, according to individuals familiar with the matter.
