CONCORD, N.C. — NASCAR chairman Brian France says a former official who's suing the organization never reported discrimination or harassment claims to her supervisors.

Mauricia Grant filed a $225 million suit against NASCAR on Tuesday, alleging racial discrimination, sexual harassment and retaliatory termination.

France said Wednesday the detailed filing was the first NASCAR learned of her claims.

"The disappointing thing is she makes a lot of claims, none of them reported," he said.
