FBI probes Supermayor Tiffany Henyards cover up of Vegas Hotel Room Encounter

A former female employee, who was Mayor Henyard's assistant, alleges retaliation, sexual harassment and discrimination after she raised concerns about an apparent non-consensual sexual encounter between her and an unnamed village trustee. A Dolton police officer said in a separate complaint filed with the Department of Human Rights that he also faced retaliatory actions for coming forward with what he witnessed.

The incident allegedly occurred during an economic development trip to Las Vegas last May.

The trip was attended by Mayor Henyard and a handful of village representatives, including her former assistant – who filed a complaint with the Illinois Department of Human Rights and two village trustees. We are not naming the woman because NBC Chicago does not name people who possibly were a victim of an unwanted sexual encounter.
