Three U.S. Secret Service officials, including communications director Anthony Guglielmi, have been placed on administrative leave amid an internal investigation into potential misconduct, CNN reported Tuesday.
The nature of the alleged misconduct remains unclear. A source familiar with the decision told CNN that all three officials work in the agency's communications office and have had their security clearances suspended and access to work devices revoked, standard measures during internal investigations.
The Secret Service confirmed to CNN that three non-law enforcement employees had been placed on leave but did not identify them. The agency said its Office of Professional Responsibility is investigating and declined to provide further details.
"The U.S. Secret Service is committed to upholding the highest standards of professionalism and integrity," an agency spokesperson said, adding that its protective mission requires "an unwavering commitment to duty, honesty, and courage."
The investigation comes during a period of heightened pressure on the agency following multiple threats and attempted attacks against President Donald Trump. In July, Guglielmi told Axios that the Secret Service had investigated roughly 10,000 threat cases during the first half of 2026, about 40% more than during the same period last year.
The agency has also faced separate internal investigations involving potential leaks. A Secret Service agent assigned to Vice President JD Vance's detail was placed on leave in July after investigators suspected the agent of disclosing information about Vance's travel.
CNN also reported that agency personnel were questioned as part of an investigation into reports surrounding a security-related decision not to use a Qatari-gifted aircraft to fly Trump out of Turkey.
Meanwhile, the Secret Service has expanded its use of surveillance technology. A privacy assessment published this summer detailed Helix, a system combining surveillance footage, facial recognition and license plate data to identify potential threats around protected locations including the White House and Capitol.
Guglielmi has led the agency's communications operation through several security crises, including assassination attempts against Trump and the 2024 shooting in Butler, Pennsylvania, which prompted the resignation of then-Secret Service Director Kimberly Cheatle and broader changes within the agency.
