A third aide to Labor Secretary Lori Chavez-DeRemer was placed on administrative leave amid an internal agency investigation into alleged misconduct, according to a news report Thursday.

Two anonymous agency officials told POLITICO that Melissa Robey, who has been serving as Chavez-DeRemer’s director of advance, was put on administrative leave Wednesday.

Robey was with Chavez-DeRemer in Hawaii as part of the Labor secretary’s “America at Work” tour, in which she is visiting all 50 states to highlight her first year in office, when she received notice that she was being placed on leave effective immediately. Administrative leave is paid and temporary, and it is not indicative of misconduct.

The DOL inspector general’s office is investigating multiple allegations against Chavez-DeRemer and her top aides, including claims that they may have violated federal policy by using taxpayer funds for the secretary’s personal travel. Chavez-DeRemer has denied wrongdoing.

Robey and a DOL spokesperson declined to comment to POLITICO on the matter.

Robey had started serving in a larger role after Chavez-DeRemer’s chief of staff and deputy chief of staff were placed on leave in early January. Both the chief of staff and the deputy chief of staff decided to resign earlier this week amid pressure from the White House, which has stood by Chavez-DeRemer since the scandal broke.

A member of the secretary's security detail has been on paid leave for more than a month amid allegations that he had an improper personal relationship with Chavez-DeRemer, who is married.

Chavez-DeRemer's husband, Shawn DeRemer, was pulled into the investigation after allegations were made by at least two female DOL employees that he touched them inappropriately at the department’s headquarters. Metropolitan Police and federal law enforcement authorities were investigating the claims, and the cases were closed without any charges being filed.

DeRemer denied wrongdoing and, through his attorney, said that the allegations were fabricated by people within DOL who are trying to undermine Chavez-DeRemer.

DOL Inspector General Anthony D’Esposito did not respond to POLITICO's request for comment.
