The U.S. Secret Service has placed three non-law enforcement employees on administrative leave following an investigation into potential misconduct. The officials, who are members of the agency’s communications office including Chief of Communications Anthony Guglielmi, have reportedly lost their security clearances and access to work devices.

The internal probe, conducted by the Office of Professional Responsibility, is investigating whether sensitive or classified information was leaked to the media. Reports indicate that the FBI and CIA may be involved in the inquiry. The agency has stated it is committed to upholding “the highest standards of professionalism and integrity” in its mission to protect high-level government officials.

This development follows a recent investigation into a member of Vice President J.D. Vance’s security detail regarding alleged information leaks. The agency is currently under heightened scrutiny following several security incidents involving President Donald Trump. Recent reports suggest the investigation may specifically involve a criminal inquiry into leaks regarding President Trump’s security arrangements, including a covert flight switch from Turkey intended to avoid potential threats from Iran.
