A Secret Service agent already under scrutiny for a major security failure is now facing a new internal investigation over a hidden marriage to a foreign national.
Miyo Perez, who was previously faulted in the breakdown at President Donald Trump’s Butler rally, has been placed on administrative leave and given “DO NOT ADMIT” status as the agency investigates potential violations of reporting rules.
According to sources familiar with the case, Perez allegedly failed to disclose her marriage to a Brazilian national for roughly nine months, raising serious internal concerns.
The issue centers on strict federal requirements that agents report close relationships with foreign nationals, especially when those relationships could present potential security risks.
Public records show Perez married the individual in April 2025, but sources say she didn’t notify the Secret Service until January, creating a significant gap that investigators are now examining closely.
Officials are also reviewing whether the foreign national was legally present in the United States at the time, including whether there were any visa issues or immigration violations tied to the situation.
This marks the third suspension for Perez in just over a year, further intensifying scrutiny around her conduct.
Her name first surfaced during congressional investigations into the Butler rally incident, where lawmakers criticized key security decisions that left major vulnerabilities exposed.
Perez was specifically faulted for failing to assign any security personnel to the sloped roof of the American Glass Building, the exact location where gunman Thomas Crooks carried out the attempted assassination.
The failure raised broader questions about planning and execution at an event that had already been flagged as high-risk.
Lawmakers also expressed concern that an inexperienced agent was placed in a critical operational role despite intelligence warnings about potential threats to Trump’s life.
Now, the focus has shifted from operational failure to personal conduct.
Investigators are examining whether Perez properly disclosed earlier contact with the Brazilian national in 2024 and whether the agency accurately tracked the relationship as it progressed.
They are also looking into whether she followed protocol when the relationship became more serious, including cohabitation and eventual marriage.
The case is reigniting long-standing concerns inside the Secret Service about how relationships with foreign nationals are handled and whether enforcement of disclosure rules is consistent.
Critics point to past incidents as evidence of deeper issues within the agency.
One frequently cited example involves a suspected Russian spy who reportedly operated within the U.S. Embassy in Moscow for years, with allegations that concerns raised internally were dismissed, per Trending Politics.
Some sources have also claimed the individual had a relationship with a senior Secret Service agent, though details remain contested.
That history is now adding fuel to concerns that warning signs can be missed or overlooked.
In Perez’s case, investigators are trying to determine whether this was a failure of individual judgment, a breakdown in internal oversight, or both.
Either way, the combination of a prior security failure and a new personal conduct investigation is putting renewed pressure on the agency.
