Holliday, best known for her Tony-winning role in Broadway's "Dreamgirls", faced pressure from her gay, lesbian and black fans when it was announced she would sing at Thursday's concert at Washington's Lincoln Memorial.
Holliday said in a statement today that she apologised for her lapse of judgement, for being uneducated on the issues and causing heartbreak for her fans.
Several prominent entertainers have declined to perform at Trump inaugural festivities. Country star Toby Keith and actor Jon Voigt are in the lineup for Thursday's concert.
