While the city and county of San Francisco have repeatedly gone to court to challenge President Donald Trump’s efforts to financially penalize so-called “sanctuary cities” for refusing to cooperate with federal immigration enforcement agencies, San Francisco faces an immigration-related lawsuit of its own.

Taxpayer Cynthia Cerletti sued San Francisco Sheriff Vicki Hennessy and the San Francisco Sheriff’s Department earlier this year in state court seeking a declaration that the sheriff has flouted federal immigration laws by refusing to allow employees to share the release dates of suspected deportable aliens with U.S. Immigration and Customs Enforcement officials.
