Labor Secretary Lori Chavez-DeRemer’s security guard resigned amid an internal probe into allegations of an “inappropriate” relationship between the two, The Post confirmed.

Brian Sloan stepped down last week after being placed on leave as the inspector general’s office investigates claims he was involved in an affair with the married secretary, sources said.

Chavez-DeRemer allegedly abused “her position” by seeking out the “inappropriate” workplace romance with her subordinate, The Post first revealed in January, citing sources and a complaint filed with the Department of Labor Office of Inspector General.

The labor secretary engaged in unprofessional interactions with her alleged paramour during trips to Las Vegas last year, according to the inspector general complaint. 

Neither the Department of Labor, a lawyer for Chavez-DeRemer nor Sloan immediately responded to The Post’s requests for comment.

Sloan’s resignation, first reported Thursday night by Politico, came soon after two of the labor secretary’s top aides stepped down over separate allegations of mistreatment of staff and misuse of taxpayer dollars.

Chavez-DeRemer’s chief of staff Jihun Han and deputy Rebecca Wright resigned earlier this month under pressure from the White House. 

A fourth staffer, Chavez-DeRemer’s Director of Advance Melissa Robey has been sidelined as well. 

A person familiar with the probe said Robey had expensed a multi-thousand-dollar limousine ride during a departmental excursion to North Dakota and turned in vouchers for excessive travel-related expenditures on other vehicles as well as hotel stays.

The initial IG complaint accused the secretary of having Han and Wright “make up” official trips to destinations she visited for personal reasons — including the ex-Oregon congresswoman’s home state; Arizona, where she has a second home with her anesthesiologist husband; and Las Vegas.

Additional complaints submitted against Han and Wright during the investigation accused the pair of exerting improper influence over junior staff, sources said.

People familiar with the probe indicated that investigators had gathered sufficient evidence of a “toxic” work environment created by the two ex-staffers, including verbal abuse and waste of departmental resources on personal travel.

IG investigators have also heard that the embattled secretary took subordinates to an Oregon strip club during an official departmental visit in April 2025.

The White House has defended Chavez-DeRemer, with press secretary Karoline Leavitt saying Jan. 15 that President Trump “thinks that she’s doing a tremendous job at the Department of Labor on behalf of American workers.”
