The play is Thomas and Sally, which is about the teenage Sally Hemings, and her owner and the father of her children, Thomas Jefferson. The play’s advertising earned it plenty of protest, and that was before it opened (it closed Oct. 29). It’s garnered much protest, including “an open letter … released by 13 black artists, calling for a public apology from MTC. The letter has received over 1,600 signatures, among them playwrights Dominique Morisseau and Lauren Gunderson (both of whom have affiliations with MTC).”
