A Secret Service agent has been placed on administrative leave as the agency investigates allegations that sensitive information about Vice President JD Vance's travel and security operations was leaked to the media, according to reports.

The unidentified agent, who serves in the Vice Presidential Protective Division, is accused of providing information for a recent MS Now story detailing Vance's travel and protective operations.

"A member of the Vice Presidential Protective Division is the subject of an administrative investigation, and potential criminal inquiry, involving allegations of compromising operational and information security," a Secret Service spokesperson told the New York Post on Thursday.

"While we will not comment on the specifics of this matter, one principle is unequivocal: Any conduct that potentially threatens the safety of a protectee will not be tolerated," the spokesperson added.

The investigation comes as the Trump administration has stepped up efforts to identify and punish government employees accused of leaking sensitive information.

According to the MS Now report, some members of Vance's protective detail were frustrated by last-minute travel changes and special requests involving the vice president and his family.

Among the examples cited was a planned Marine Two flight so Vance and his son could travel to Joint Base Andrews for a golf lesson. The helicopter trip was later canceled because of bad weather, though the outlet reported that some agents viewed the request as inappropriate.

The report also stated Vance and second lady Usha Vance took several last-minute helicopter trips while house hunting in northern Virginia.

An administration official pushed back on the criticism, telling the Post that White House schedules are subject to change without notice.

"Events at the White House can often arise unexpectedly. Those events must override previously planned travel," the official said.

"The vice president is a father who dedicates as much time as possible to his young and growing family," the official continued.

"Plans for the vice president to travel to the base's golf course were made because the base was secure and offered the added benefit of not impacting a public golf course," the official continued. The use of a public golf course could have necessitated a full or partial closure during the vice president's visit.

The source also said helicopter travel is often preferred because it avoids the traffic disruptions and road closures associated with motorcades.

The investigation comes as Secret Service Director Sean Curran has warned of an increasingly dangerous threat environment facing public officials.

"I think the environment has become very volatile and that's just across the board, not just to our protectees but local officials. The threat picture and environment is as large as I've ever seen it," Curran said Wednesday, noting the agency has opened about 10,000 threat investigations so far this year.
