A consultant the Chicago Blackhawks hired to improve relationships with American Indian tribes has filed a lawsuit accusing the team, its charity foundation and its CEO of fraud, breach of contract and sexual harassment.

Nina Sanders filed the civil action late Tuesday in Cook County Circuit Court. She alleges in the lawsuit that the Blackhawks were facing intense public pressure to change their name and logo in 2020. The team's CEO, Danny Wirtz, hired her that year to serve as a tribal liaison.
