Chuck Edwards has raised concerns about unwanted attention and fears of retaliation, according to a new report.
The development comes as Edwards faces an ongoing ethics probe and broader congressional oversight.
The aide's account adds fresh context to the scrutiny surrounding the Republican representative from North Carolina.
The report highlights a pattern of attention directed at young female staff members, which has drawn criticism and workplace conduct.
The House Ethics Committee is already examining the matter, with a separate inquiry by the Government Accountability Office also underway.
The situation has intensified calls for transparency and accountability in congressional operations.
