From FOX:

Rashad will portray DIANA DUBOIS, a powerhouse from one of New York’s oldest and most prominent African-American families. As the mother of ambitious city councilman Angelo Dubois (guest star Taye Diggs), she has her sights set on higher office for her only son, and she’ll stop at nothing to groom him. Diana’s interactions with Cookie, Lucious and the rest of the Lyon clan will lay bare the stark class divides that can exist, even within the black community.”
