Artist Judy Baca is pushing back against allegations from former employees who claim she improperly benefited from a $5 million grant tied to the expansion of her landmark mural, The Great Wall of Los Angeles, according to a report in the Los Angeles Times.

The accusations come from 10 former employees of the Social and Public Art Resource Center, or SPARC, the Venice-based nonprofit Baca co-founded in 1976. Several former staff members, including two managers, told the Times that Baca blurred the line between SPARC and her private business, Judy Baca Inc., and personally profited from grant funds intended for the mural’s expansion.
