Former official sues NASCAR over harassment claims

A former racing official is suing NASCAR, alleging racial and sexual discrimination, sexual harassment and wrongful termination.

Mauricia Grant worked as a technical inspector responsible for certifying cars in NASCAR's second-tier Nationwide Series from January 2005 until she was fired last October.

Grant, who is black, alleges she was referred to as "Nappy Headed Mo" and "Queen Sheba," by white co-workers. She also claims she often was told she worked on "colored people time," and was frightened by one official who routinely made references to the Ku Klux Klan.

The lawsuit, which seeks $250 million, was filed Tuesday in the U.S. District Court for the Southern District of New York.
