On Thursday evening, New York City Mayor Zohran Mamdani shocked the Congressional Hispanic Caucus when he appeared on MS NOW to endorse democratic socialist challenger Darializa Avila Chevalier over sitting Upper Manhattan Rep. Adriano Espaillat. Mamdani, after all, had privately pledged that he would support Espaillat, the five-term incumbent who was one of the first former Andrew Cuomo supporters to support him. Making matters worse, Mamdani credited Avila Chevalier for having “secured the release of our neighbors from undue ICE custody.” But it was Espaillat, the chairman of the Hispanic Caucus, who drafted legislation to rein in the agency, and even joined a lawsuit to force the administration to give Congress access to federal detention facilities.
