Two hundred USC professors on Tuesday demanded the resignation of university President C.L. Max Nikias, saying he had “lost the moral authority to lead” in the wake of revelations that a campus gynecologist was kept on staff for decades despite repeated complaints of misconduct.

In a letter to the USC Board of Trustees, the faculty members wrote that they had come together to “express our outrage and disappointment over the mounting evidence of President Nikias’ failure to protect our students, our staff, and our colleagues from repeated and pervasive sexual harassment and misconduct.”
